Grammy AwardGrammy Award
The Grammy Awards (originally the Gramophone Awards), presented by the Recording Academy (an association of Americans professionally involved in the recorded music industry) for outstanding achievements in the recording industry, is one of four major music awards shows held annually in the United States (the Billboard Music Awards, the American Music Awards, and the Rock and Roll Hall of Fame Induction Ceremony, make up the rest). However, the Grammys, usually held in February, (last of what are considered the "big three" music awards shows, including the BMA and AMA shows) are considered the approximate equivalent to the Oscars, in the music world.
Like the Oscars, the Grammys, which currently have 108 categories within 30 genres of music (such as pop, gospel, and rap), are voted upon by peers - voting members of the Recording Academy - rather than being based upon popularity (as with the AMAs) or sales and chart achievements (the BMAs).
The awards are named for the trophy which the winner receives - a small gilded statuette of a gramophone, handcrafted by Billings Artworks. The awards ceremony features performances by prominent artists, and some of the more prominent Grammys are presented in a widely-viewed televised ceremony.
Some feel that because Grammy voters tend to vote conservatively, and are marketed to by record companies, the most widely-recognized Grammys tend to go to either well-established artists or those being hyped by the recording industry. Hence, the Grammys are not taken seriously by some musicians and music fans. In fact, many artists who are placed in high regard, artistically, by many fans and critics (such as Elvis Presley, Mariah Carey, Garth Brooks, Pink Floyd, Kenny Rogers, The Rolling Stones, Led Zeppelin, Radiohead, ) have been awarded very few Grammys.
Of the "big three" music awards shows, the Grammys are the highest rated.
Unlike the Academy Awards, for which the eligibility period begins January 1, the eligibility period for the Grammys begins October 1, which results in September being considered the Christmas sales period for the music industry (in which artists generally release big albums to qualify for the next year's Grammy). So, for example, John Lennon & Yoko Ono's album Double Fantasy was released in November, 1980, a month-and-a-half too late to qualify for the 1981 Grammys, and thus eligible for the 1982 awards (it eventually won the Grammy Award for Album of the Year).
The Grammys are currently broadcast on CBS.
Pat Metheny and the Pat Metheny Group have won 16 Grammys in total, including six consecutive awards for six consecutive albums. Metheny, as of the 2004 Grammy Awards, holds the record for Grammy wins in the most different categories:
Session drummer Hal Blaine played on six consecutive records which won Record of the Year:
Legendary Opera Diva Leontyne Price has won 18 awards
Soul and R&B legend Aretha Franklin has won 11 awards for Best Female R&B Vocal Performance, including 8 consecutive (and the first 8 ever awarded) awards in the category:
Conductor Sir Georg Solti holds the record for most Grammys won, having won a total of thirty-eight awards before his death in 1997.
The most Grammys won in a single night is eight -- a record shared by Michael Jackson (1984), and Carlos Santana (2000).
Christopher Cross (Grammy Awards of 1981) and Norah Jones (Grammy Awards of 2003) are the only artists to receive the "Big Four" (Record of the Year, Album of the Year, Song of the Year, and Best New Artist) in a single ceremony.
Béla Fleck has been nominated in more categories than any other musician, namely country, pop, jazz, bluegrass, classical, folk, and spoken word, as well as composition and arranging.

On August 29, 2005, Hurricane Katrina made landfall in Louisiana and Mississippi. Reggae. Hurricane Jeanne in 2004 was only a tropical storm when it made a glancing blow on Haiti, but the flooding and mudslides it caused killed over 3,000 people.
Rap. A tropical cyclone need not be particularly strong to cause memorable damage; Tropical Storm Allison in June 2001 had its name retired for killing 41 people and causing over $5 billion damage in East Texas, even though it never became a hurricane; the damage from Allison was mostly due to flooding, not winds or storm surge. R&B. Hurricanes may have formed there prior to 1960 but were not observed until weather satellites began monitoring the Earth's oceans in that year. Production and engineering.

Similarly, a gust caused by Typhoon Paka over Guam was recorded at 236 mph (380 km/h); however, this reading had to be discarded, since the anemometer was damaged by the storm.
Gospel. Typhoon Nancy in 1961 had recorded wind speeds of 213 mph (343 km/h), but recent research indicates that wind speeds from the 1940s to the 1960s were gauged too high, and this is no longer considered the fastest storm on record. Folk. For comparison, these speeds are encountered at the center of a strong tornado, but Camille was much larger and long-lived than any tornado. Film/TV/Media. Camille was the only storm to actually strike land while at that intensity, making it, with 190 mph (305 km/h) sustained winds and 210 mph (335 km/h) gusts, the strongest tropical cyclone of record to ever hit land. Disco. Tip does not hold the record for fastest sustained winds in a cyclone alone; Typhoon Keith in the Pacific, and Hurricane Camille and Hurricane Allen in the North Atlantic currently share this record as well , although recorded wind speeds that fast are suspect, since most monitoring equipment is likely to be destroyed by such conditions.
Dance. It weakened before striking Japan. Country.

The most Grammys won in a single night is eight -- a record shared by Michael Jackson (1984), and Carlos Santana (2000). Tropical cyclones that cause massive destruction are fortunately rare, but when they happen, they can cause damage in the thousands of lives and the billions of dollars. Conductor Sir Georg Solti holds the record for most Grammys won, having won a total of thirty-eight awards before his death in 1997. This statistic needs refining because the variables being tested are not normally distributed with equal variances, but it may provide the best evidence yet that the impact of global warming on hurricane intensity has been detected.
Soul and R&B legend Aretha Franklin has won 11 awards for Best Female R&B Vocal Performance, including 8 consecutive (and the first 8 ever awarded) awards in the category:. Under the assumption that the six basins are statistically independent except for the effect of global warming, Stoft has carried out the obvious paired t-test and found that the null-hypothesis of no impact of global warming on the percentage of category 4 & 5 hurricanes can be rejected at the 0.1% level—there is only a 1 in 1000 chance of simultaneously finding the observed six increases in the cat-4&5 percentages. Legendary Opera Diva Leontyne Price has won 18 awards. do not undertake any such test. Session drummer Hal Blaine played on six consecutive records which won Record of the Year:. Unfortunately Webster et al. Metheny, as of the 2004 Grammy Awards, holds the record for Grammy wins in the most different categories:. But if the local oscillations are not synchronized by some as-yet-unidentified global oscillation, the independence of the basins allows joint statistical tests that are more powerful than any set of individual basin tests.
Pat Metheny and the Pat Metheny Group have won 16 Grammys in total, including six consecutive awards for six consecutive albums. Because each individual basin may be subject to intra-basin oscillations similar to the AMO, any single-basin statistic remains open to question. . analyze the slightly less relevant percentage of hurricanes in the combined categories 4 and 5, and find that this percentage has increased in each of six distinct hurricane basins: North Atlantic, North East and North West Pacific, South Pacific, and North and South Indian. The Grammys are currently broadcast on CBS. While Emanuel analyzes total annual energy dissipation, Webster et al. So, for example, John Lennon & Yoko Ono's album Double Fantasy was released in November, 1980, a month-and-a-half too late to qualify for the 1981 Grammys, and thus eligible for the 1982 awards (it eventually won the Grammy Award for Album of the Year). .
Unlike the Academy Awards, for which the eligibility period begins January 1, the eligibility period for the Grammys begins October 1, which results in September being considered the Christmas sales period for the music industry (in which artists generally release big albums to qualify for the next year's Grammy). So, both a natural variation (such as the AMO) and global warming could have made contributions to the warming of the tropical Atlantic over the past decades, but an exact attribution is so far impossible to make. Of the "big three" music awards shows, the Grammys are the highest rated. Emanuel, however, found the recent temperature increase was outside the range of previous oscillations. In fact, many artists who are placed in high regard, artistically, by many fans and critics (such as Elvis Presley, Mariah Carey, Garth Brooks, Pink Floyd, Kenny Rogers, The Rolling Stones, Led Zeppelin, Radiohead, ) have been awarded very few Grammys. K. Hence, the Grammys are not taken seriously by some musicians and music fans. The question then becomes: what caused the observed increase in sea surface temperatures? In the Atlantic, it could be due to the Atlantic Multidecadal Oscillation (AMO), a 50–70 year pattern of temperature variability.
Some feel that because Grammy voters tend to vote conservatively, and are marketed to by record companies, the most widely-recognized Grammys tend to go to either well-established artists or those being hyped by the recording industry. Both Emanuel and Webster et al., consider the sea surface temperature as of key importance in the development of cyclones. The awards ceremony features performances by prominent artists, and some of the more prominent Grammys are presented in a widely-viewed televised ceremony. I.e., while the number of cyclones decreased overall, the number of very strong cyclones increased. The awards are named for the trophy which the winner receives - a small gilded statuette of a gramophone, handcrafted by Billings Artworks. The main finding is that while the number of cyclones "decreased in all basins except the North Atlantic during the past decade" there is a "large increase in the number and proportion of hurricanes reaching categories 4 and 5". Like the Oscars, the Grammys, which currently have 108 categories within 30 genres of music (such as pop, gospel, and rap), are voted upon by peers - voting members of the Recording Academy - rather than being based upon popularity (as with the AMAs) or sales and chart achievements (the BMAs). published an article in Science 309, 1844-1846 examining "changes in tropical cyclone number, duration, and intensity" over the last 35 years, a period where satellite data is available.

Along similar lines, P.J. Best Contemporary World Music Album. Emanuel further predicts "a substantial increase in hurricane-related losses in the twenty-first century". Best Traditional World Music Album.

Other approaches have been suggested over time, including cooling the water under a tropical cyclone by towing icebergs into the tropical oceans; dropping large quantities of ice into the eye at very early stages so that latent heat is absorbed by ice at the entrance (storm cell perimeter bottom) instead of heat energy being converted to kinetic energy at high altitudes vertically above; covering the ocean in a substance that inhibits evaporation; or blasting the cyclone apart with nuclear weapons. Best Song Written for a Motion Picture, Television or Other Visual Media (previously in the "composing and arranging" field). Today it is known that silver iodide seeding is not likely to have an effect because the amount of supercooled water in the rainbands of a tropical cyclone is too low.. Best Compilation Soundtrack Album for a Motion Picture, Television or Other Visual Media. The project was dropped after it was discovered that eyewall replacement cycles occur naturally in strong hurricanes, casting doubt on the result of the earlier attempts.
Best Disco Recording. Because there was so much uncertainty about the behavior of these storms, the federal government would not approve seeding operations unless the hurricane had a less than 10 percent chance of making landfall within 48 hours. Best Electronic/Dance Album. In an earlier episode, disaster struck when a hurricane east of Jacksonville, Florida, was seeded, promptly changed its course, and smashed into Savannah, Georgia. Best Dance Recording (previously in "Pop"). The winds of Hurricane Debbie dropped as much as 30 percent, but then regained their strength after each of two seeding forays. Best New Country & Western Artist. It was thought that the seeding would cause supercooled water in the outer rainbands to freeze, causing the inner eyewall to collapse and thus reducing the winds.
Best Bluegrass Album. In the 1960s and 1970s, the United States government attempted to weaken hurricanes in its Project Stormfury by seeding selected storms with silver iodide. Best Country Album. In the Atlantic ocean, such tropical-derived cyclones of higher latitudes can be violent and may occasionally remain at hurricane-force wind speeds when they reach Europe as a European windstorm. Best Country Song. When a tropical cyclone reaches higher latitudes or passes over land, it may merge with weather fronts or develop into a frontal cyclone, also called extratropical cyclone. Best Country & Western Single. Even after a tropical cyclone is said to be extratropical or dissipated, it can still have tropical storm force (or occasionally hurricane force) winds and drop several inches of rainfall.

For emergency preparedness, actions should be timed from when a certain wind speed will reach land, not from when landfall will occur. Best Country Performance by a Duo or Group with Vocal. In fact, for a storm moving inland, the landfall area experiences half the storm before the actual landfall.
Best Country Performance, Duo or Group - Vocal or Instrumental. Naturally, storm conditions may be experienced on the coast and inland well before landfall. Best Male Country Vocal Performance. Officially, "landfall" is when a storm's center (the center of the eye, not its edge) reaches land. Best Female Country Vocal Performance. They attribute the lack of improvement in intensity forecasting to the complexity of tropical systems and an incomplete understanding of factors that affect their development. Best Vocal Arrangement for Two or More Voices. But while track forecasts have become more accurate than 20 years ago, scientists say they are less skillful at predicting the intensity of tropical cyclones.
Best Instrumental Arrangement Accompanying Vocalist(s). High-speed computers and sophisticated simulation software allow forecasters to produce computer models that forecast tropical cyclone tracks based on the future position and strength of high- and low-pressure systems. Best Instrumental Arrangement. With their understanding of the forces that act on tropical cyclones, and a wealth of data from earth-orbiting satellites and other sensors, scientists have increased the accuracy of track forecasts over recent decades. Best Arrangement. Because of the forces that affect tropical cyclone tracks, accurate track predictions depend on determining the position and strength of high- and low-pressure areas, and predicting how those areas will change during the life of a tropical system.

Such a track direction change is termed recurve. A hurricane moving from the Atlantic toward the Gulf of Mexico, for example, will recurve to the north and then northeast if it encounters winds blowing northwestward toward a high-pressure system passing over North Africa. Best Spoken Comedy Album. Finally, when a tropical cyclone moves into higher latitude, its general track around a high-pressure area can be deflected significantly by winds moving toward a low-pressure area. Best Comedy Album. (Much of that is due to the conservation of angular momentum - air is drawn in from an area much larger than the cyclone such that the tiny angular velocity of that air will be magnified greatly when the distance to the storm center shrinks.).
Best New Classical Artist. The Coriolis acceleration also initiates cyclonic rotation, but it is not the driving force that brings this rotation to high speeds. Best Classical Crossover Album. Thus, tropical cyclones in the Northern Hemisphere, which commonly move west in the beginning, normally turn north (and are then usually blown east), and cyclones in the Southern Hemisphere are deflected south, if no strong pressure systems are counteracting the Coriolis Acceleration. Best Classical Album. The southern part is pulled south, but since it is closer to the equator, the Coriolis force is a bit weaker there). Best Classical Contemporary Composition. in the north, the northern part of the cyclone has winds to the west, and the Coriolis force pulls them slightly north.

This acceleration causes cyclonic systems to turn towards the poles in the absence of strong steering currents (i.e. Best Small Ensemble Performance (with or without conductor). The earth's rotation also imparts an acceleration (termed the Coriolis Acceleration or Coriolis Effect). Best Instrumental Soloist Performance (without orchestra). Also, in the area of the North Atlantic where hurricanes form, trade winds, which are prevailing westward-moving wind currents, steer tropical waves (precursors to tropical depressions and cyclones) westward from off the African coast toward the Caribbean and North America. Best Instrumental Soloist(s) Performance (with orchestra). Over the North Atlantic Ocean, tropical systems are steered generally westward by the east-to-west winds on the south side of the Bermuda High, a persistent high-pressure area over the North Atlantic.

A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extratropical cyclone. Best Alternative Music Album. Extratropical cyclones can also be dangerous because their low-pressure centers cause powerful winds.
Grammy Trustees Award. From space, extratropical storms have a characteristic "comma-shaped" cloud pattern. Grammy Tech Award. A tropical cyclone can become extratropical as it moves toward higher latitudes if its energy source changes from heat released by condensation to differences in temperature between air masses; more rarely, an extratropical cyclone can transform into a subtropical storm, and from there into a tropical cyclone. Grammy Lifetime Achievement Award. An extratropical cyclone is a storm that derives energy from horizontal temperature differences, which are typical in higher latitudes. Grammy Legend Award. Several of these relate to the formation or dissipation of tropical cyclones.

The Joint Typhoon Warning Center classifies typhoons with wind speeds of at least 150 mi/h (67 m/s or 241 km/h, equivalent to a strong Category 4 storm) as Super Typhoons. 1988 - Aretha. The National Hurricane Center classifies hurricanes of Category 3 and above as Major Hurricanes. 1986 - "Freeway of Love". In fact, tropical systems of less than hurricane strength can produce significant damage and human casualties, especially from flooding and landslides. 1982 - "Hold On, I'm Comin'". For instance, a Category 2 hurricane that strikes a major urban area will likely do more damage than a large Category 5 hurricane that strikes a mostly rural region.
1975 - "Ain't Nothing Like The Real Thing". Lower-category storms can inflict greater damage than higher-category storms, depending on factors such as local terrain and total rainfall. 1974 - "Master of Eyes". The rankings are not absolute in terms of effects. 1973 - Young, Gifted, and Black. A Category 1 storm has the lowest maximum winds, a Category 5 hurricane has the highest. 1972 - "Bridge Over Troubled Water". Hurricanes are ranked according to their maximum winds using the Saffir-Simpson Hurricane Scale.
1971 - "Don't Play That Song". Eventually the outer eyewall replaces the inner one completely and the storm can be the same intensity as it was previously or, in some cases, even stronger. 1970 - "Share Your Love With Me". the maximum winds die off a bit and the central pressure goes up). 1969 - "Chain of Fools". During this phase, the tropical cyclone is weakening (i.e. 1968 - "Respect". At this point, some of the outer rainbands may organize into an outer ring of thunderstorms that slowly moves inward and robs the inner eyewall of its needed moisture and momentum.
1971 Simon & Garfunkel - "Bridge Over Troubled Water". When cyclones reach peak intensity they usually - but not always - have an eyewall and radius of maximum winds that contract to a very small size, around 5 to 15 miles. 1970 5th Dimension - "Aquarius/Let the Sunshine In". Eyewall replacement cycles naturally occur in intense tropical cyclones. Robinson". Intense, mature hurricanes can sometimes exhibit an inward curving of the eyewall top that resembles a football stadium: this phenomenon is thus sometimes referred to as stadium effect. 1969 Simon & Garfunkel - "Mrs. Maximum sustained winds in the strongest tropical cyclones have been measured at more than 85 m/s (165 knots, 190 mph, 305 km/h).

At hurricane and typhoon intensity, a tropical cyclone tends to develop an eye, an area of relative calm (and lowest atmospheric pressure) at the center of the circulation. Best Jazz Instrumental Performance, Individual or Group (1998, 2000). Government weather services assign first names to systems that reach this intensity (thus the term named storm). Best Contemporary Jazz Performance/Album (1993, 1994, 1996, 1999, 2003). At this point, the distinctive cyclonic shape starts to develop, though an eye is usually not present.
Best Instrumental Composition (1991). A tropical storm is an organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds between 17 and 33 meters per second (34–63 knots, 39–73 mph, or 62–117 km/h). Best Jazz Fusion Performance (1983, 1984, 1985, 1988, 1990). It is already becoming a low-pressure system, however, hence the name "depression". It has no eye, and does not typically have the spiral shape of more powerful storms. A tropical depression is an organized system of clouds and thunderstorms with a defined surface circulation and maximum sustained winds of less than 17 metres per second (33 knots, 38 mph, or 62 km/h).
Tropical cyclones are classified into three main groups: tropical depressions, tropical storms, and a third group whose name depends on the region. A strong tropical cyclone consists of the following components. The following areas spawn tropical cyclones only very rarely. There are seven main basins of tropical cyclone formation:.
It is estimated that such conditions occur only once every 400 years. A combination of a pre-existing disturbance, upper level divergence and a monsoon-related cold spell led to Typhoon Vamei at only 1.5 degrees north of the equator in 2001. Hurricane Ivan of 2004 developed within 10 degrees of the equator. These conditions are extremely rare, and such storms are believed to form at most once per century.
However, it is possible for tropical cyclones to form within this boundary if there is another source of initial rotation. Because the Coriolis effect initiates and maintains tropical cyclone rotation, such cyclones almost never form or move within about 10 degrees of the equator , where the Coriolis effect is weakest. Nearly all of them form between 10 and 30 degrees of the equator and 87% form within 20 degrees of it. Most tropical cyclones form in a worldwide band of thunderstorm activity called the Intertropical convergence zone (ITCZ).
Worldwide, an average of 80 tropical cyclones form each year. Southern Hemisphere activity peaks in mid-February to early March. In the Southern Hemisphere, tropical cyclone activity begins in late October and ends in May. In the North Indian basin, storms are most common from April to December, with peaks in May and November.
The Northwest Pacific sees tropical cyclones year-round, with a minimum in February and a peak in early September. The Northeast Pacific has a broader period of activity, but in a similar timeframe to the Atlantic. The statistical peak of the North Atlantic hurricane season is September 10. In the North Atlantic, a distinct hurricane season occurs from June 1 to November 30, sharply peaking from late August through September.
However, each particular basin has its own seasonal patterns. Worldwide, tropical cyclone activity peaks in late summer when water temperatures are warmest. These include:. Only specific weather disturbances can result in tropical cyclones.
Tropical cyclones occasionally form despite not meeting these conditions. Five factors are necessary to make tropical cyclone formation possible:. The formation of tropical cyclones is the topic of extensive ongoing research, and is still not fully understood. The high cirrus clouds may be the first signs of an approaching hurricane.
This outflow produces high, thin cirrus clouds that spiral away from the center. These originate from air that has released its moisture and is expelled at high altitude through the "chimney" of the storm engine. While the most obvious motion of clouds is toward the center, tropical cyclones also develop an upper-level (high-altitude) outward flow of clouds. Scientists at the National Center for Atmospheric Research estimate that a hurricane releases heat energy at the rate of 50 to 200 trillion watts -- about the amount of energy released by exploding a 10-megaton nuclear bomb every 20 minutes .
As a result, when a tropical cyclone passes over land, its strength diminishes rapidly. The evaporation of this moisture is accelerated by the high winds and reduced atmospheric pressure in the storm, resulting in a positive feedback loop. In order to continue to drive its heat engine, a tropical cyclone must remain over warm water, which provides the atmospheric moisture needed. By contrast, mid-latitude cyclones, for example, draw their energy mostly from pre-existing horizontal temperature gradients in the atmosphere.
Condensation as a driving force is what primarily distinguishes tropical cyclones from other meteorological phenomena, and because this is strongest in a tropical climate, this defines the initial domain of the tropical cyclone. If the right conditions persist and allow it to create a feedback loop by maximizing the energy intake possible, for example, such as high winds to increase the rate of evaporation, they can combine to produce the violent winds, incredible waves, torrential rains, and floods associated with this phenomenon. The factors to form a tropical cyclone include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds aloft. The orbital revolution of the Earth causes the system to spin, an effect known as the Coriolis force, giving it a cyclone characteristic and affecting the trajectory of the storm.
Factors such as a continued lack of equilibrium in air mass distribution would also give supporting energy to the cyclone. This gives rise to factors that give the system enough energy to be self-sufficient and cause a positive feedback loop where it can draw more energy as long as the source of heat, warm water, remains. Continued condensation leads to higher winds, continued evaporation, and continued condensation, feeding back into itself. Therefore, a tropical cyclone can be thought of as a giant vertical heat engine supported by mechanics driven by physical forces such as the rotation and gravity of the Earth.
Its primary energy source is the release of the heat of condensation from water vapor condensing at high altitudes, the heat ultimately derived from the sun. Structurally, a tropical cyclone is a large, rotating system of clouds, wind and thunderstorms. . The word cyclone is from the Greek "κύκλος", meaning "circle." An Egyptian word Cykline meaning to "to spin" has been cited as a possible origin.
The word hurricane is derived from the name of a native Caribbean Amerindian storm god, Huracan, via Spanish huracán. See tuphōn for more information. Portuguese tufão is also related to typhoon. The word typhoon has two possible origins:.
There are many regional names for tropical cyclones, including Bagyo in the Philippines and Taino in Haiti. Terms used in weather reports for tropical cyclones that have surface winds over 64 knots (73.6 mph) or 32 m/s vary by region:. . While they can be highly destructive, tropical cyclones are an important part of the atmospheric circulation system, which moves heat from the equatorial region toward the higher latitudes.
In meteorology, a tropical cyclone (also referred to as a tropical depression, tropical storm, typhoon, or hurricane depending on strength and geographical context) is a type of low pressure system which generally forms in the tropics. Transportation difficulties - Tropical cyclones often destroy key bridges, overpasses, and roads, complicating efforts to transport food, clean water, and medicine to the areas that need it. Power outages - Tropical cyclones often knock out power to tens or hundreds of thousands of people (or occasionally millions if a large urban area is affected), prohibiting vital communication and hampering rescue efforts. Infections of cuts and bruises can be greatly amplified by wading in sewage-polluted water.
One of the most common post-hurricane injuries is stepping on a nail in storm debris, leading to a risk of tetanus or other infection. Disease - The wet environment in the aftermath of a tropical cyclone, combined with the destruction of sanitation facilities and a warm tropical climate, can induce epidemics of disease which claim lives long after the storm passes. While these tornadoes are normally not as strong as their non-tropical counterparts, they can still cause tremendous damage. Tornado activity - The broad rotation of a hurricane often spawns tornadoes.
Rivers and streams flood, roads become impassable, and landslides can occur. Heavy rain - The thunderstorm activity in a tropical cyclone causes intense rainfall. This is the worst effect, as cyclones claim 80% of their victims when they first strike shore. Storm surge - Tropical cyclones cause an increase in sea level, which can flood coastal communities.
High winds also turn loose debris into flying projectiles, making the outdoor environment even more dangerous. High winds - Hurricane strength winds can damage or destroy vehicles, buildings, bridges, etc. Such weakening is generally temporary unless it meets other conditions above. An outer eye wall forms (typically around 50 miles from the center of the storm), choking off the convection toward the inner eye wall.
These storms are extratropical cyclones. This does not necessarily mean the death of the storm, but the storm will lose its tropical characteristics. It enters colder waters. (Such, however, can strengthen the non-tropical system as a whole.).
It can be weak enough to be consumed by another area of low pressure, disrupting it and joining to become a large area of non-cyclonic thunderstorms. It experiences wind shear, causing the convection to lose direction and the heat engine to break down. Without warm surface water, the storm cannot survive. It remains in the same area of ocean for too long, drawing heat off of the ocean surface until it becomes too cool to support the storm.
However, many storm fatalities occur in mountainous terrain, as the dying storm unleashes torrential rainfall which can lead to deadly floods and mudslides. If a storm is over mountains for even a short time, it can rapidly lose its structure. There is, however, a chance they could regenerate if they manage to get back over open warm water. Most strong storms lose their strength very rapidly after landfall, and become disorganized areas of low pressure within a day or two.
It moves over land, thus depriving it of the warm water it needs to power itself, and quickly loses strength. Tropical cyclones owe this unique characteristic to the warm core at the center of the storm. Winds at the surface are strongly cyclonic, weaken with height, and eventually reverse themselves. Outflow: The upper levels of a tropical cyclone feature winds headed away from the center of the storm with an anticyclonic rotation.
The heaviest wind damage occurs where a hurricane's eyewall passes over land. Eyewall: A band around the eye of greatest wind speed, where clouds reach highest and precipitation is heaviest. In weaker cyclones, the CDO covers the circulation center, resulting in no visible eye. The eye is normally circular in shape, and may range in size from 8 km to 200 km (5 miles to 125 miles) in diameter.
Eyes are home to the coldest temperatures of the storm at the surface, and the warmest temperatures at the upper levels. Weather in the eye is normally calm and free of clouds (however, the sea may be extremely violent). Eye: A strong tropical cyclone will harbor an area of sinking air at the center of circulation. The classic hurricane contains a symmetrical CDO, which means that it is perfectly circular and round on all sides.
This contains the eye wall, and the eye itself. Central Dense Overcast (CDO): The Central Dense Overcast is a dense shield of very intense thunderstorm activity that make up the inner portion of the hurricane. Thus, at any given altitude (except close to the surface where water temperature dictates air temperature) the environment inside the cyclone is warmer than its outer surroundings. This heat is distributed vertically, around the center of the storm.
Warm core: Tropical cyclones are characterized and driven by the release of large amounts of latent heat of condensation as moist air is carried upwards and its water vapor condenses. The pressures recorded at the centers of tropical cyclones are among the lowest that occur on Earth's surface at sea level. Surface low: All tropical cyclones rotate around an area of low atmospheric pressure near the Earth's surface. The Great Lakes A storm system that appeared similar to a tropical cyclone formed in 1996 on Lake Huron it formed an eye and could have breifly been sub-tropical.
It formed from a thunderstorm formation in Borneo that moved into the South China Sea. It caused flooding in southern Malaysia and some damage in Singapore. However, in December 2001, Typhoon Vamei formed in the Southern South China Sea and made landfall in Malaysia. Areas within ten degrees laditude of the equator do not experience a significant coriolis force, a vital ingredient in tropical cyclone formation.
Southern South China Sea Tropical cyclones normally do not develop in the Southern South China Sea due to its close proximity to the equator. Australia: SE Indian Basin includes the eastern part of the Indian ocean and the northern and western part of the Australian basin. Australia: SW Pacific Basin includes the eastern part of Australia and the Fiji area. before being transformed into an extratropical low or absorbed into other systems of low pressure.
Vince's origin was the northernmost in the eastern Atlantic ever recorded, and Vince was the first storm in recorded history to reach the Iberian Peninsula as a tropical cyclone, i.e. Northeastern Atlantic Ocean: In October 2005, Hurricane Vince formed near Madeira, then moved northeastward, passing south of the Portuguese south coast, and made landfall in southwestern Spain as a tropical depression. However, there is debate on whether these storms were tropical in nature. Such cyclones formed in September 1947, September 1969, January 1982, September 1983, and January 1995.
Mediterranean Sea: Storms which appear similar to tropical cyclones in structure sometimes occur in the Mediterranean basin. They affect the islands of Polynesia in exceptional instances. Most of the storms that enter this region formed farther west in the Southwest Pacific. Eastern South Pacific: Tropical cyclone formation is rare in this region; when they do form, it is frequently linked to El Niño episodes.
However, this region is commonly frequented by tropical cyclones that form in the much more favorable Eastern North Pacific Basin. Central North Pacific: Shear in this area of the Pacific Ocean severely limits tropical development. The January storm is thought to have reached tropical storm intensity based on scatterometre winds. However, three tropical cyclones have been observed here — a weak tropical storm in 1991 off the coast of Africa, Hurricane Catarina (sometimes also referred to as Aldonça), which made landfall in Brazil in 2004 as a Category 1 hurricane, and a smaller storm in January 2004, east of Salvador, Brazil.
Southern Atlantic Ocean: A combination of cooler waters, the lack of an ITCZ, and wind shear makes it very difficult for the Southern Atlantic to support tropical activity. Cyclones forming here impact Madagascar, Mozambique, Mauritius, and Kenya, and these nations issue forecasts and warnings for the basin. Southwestern Indian Ocean: This basin is the least understood, due to a lack of historical data. Southeastern Indian Ocean: Tropical activity in this region affects Australia and Indonesia, and is forecast by those nations.
Rarely, a tropical cyclone formed in this basin will affect the Arabian Peninsula. Nations affected by this basin include India, Bangladesh, Sri Lanka, Thailand, Myanmar, and Pakistan, and all of these countries issue regional forecasts and warnings. Hurricanes which form in this basin have historically cost the most lives — most notably, the 1970 Bhola cyclone killed 200,000. This basin's season has an interesting double peak; one in April and May before the onset of the monsoon, and another in October and November just after.
Northern Indian Ocean: This basin is divided into two areas, the Bay of Bengal and the Arabian Sea, with the Bay of Bengal dominating (5 to 6 times more activity). South Western Pacific Ocean: Tropical activity in this region largely affects Australia and Oceania, and is forecast by Australia and Papua New Guinea. In the U.S., the Central Pacific Hurricane Center is responsible for forecasting the western part of this area while the National Hurricane Center is responsible for the eastern part. Storms that form here can affect western Mexico, Hawaii, northern Central America, and on extremely rare occasions, California.
Eastern North Pacific Ocean: This is the second most active basin in the world, and the most dense (a large number of storms for a small area of ocean). National meteorology organizations and the Joint Typhoon Warning Center (JTWC) are responsible for issuing forecasts and warnings in this basin. The eastern coasts of Taiwan and Philippines also have the highest tropical cyclone landfall frequency in the world. This is by far the most active basin, accounting for one-third of all tropical cyclone activity in the world.
Western North Pacific Ocean: Tropical storm activity in this region frequently affects China, Japan, the Philippines, and Taiwan, but also many other countries in South-East Asia, such as Vietnam, South Korea and Indonesia, plus numerous Oceanian islands. Many of the more intense Atlantic storms are Cape Verde-type hurricanes, which form off the west coast of Africa near the Cape Verde islands. The coast of Atlantic Canada receives hurricane landfalls on rare occasion, such as Hurricane Juan in 2003. Gulf Coast and occasionally New Jersey, New York and New England (usually hurricanes weaken to tropical storms before they reach these northern regions).
Additionally, they can hit the coast of the U.S., especially Florida, North Carolina, the U.S. Hurricanes that strike Mexico, Central America, and Caribbean island nations, often do intense damage, as hurricanes are deadlier over warmer water. National Hurricane Center (NHC) based in Miami, Florida, issues forecasts for storms for all nations in the region; the Canadian Hurricane Centre, based in Halifax, Nova Scotia, also issues forecasts and warnings for storms expected to affect Canadian territory and waters. The U.S.
Venezuela, the south-east of Canada and Atlantic "Macaronesian" islands are also occasionally affected. The United States Atlantic coast, Mexico, Central America, the Caribbean Islands and Bermuda are frequently affected by storms in this basin. The average is about ten. Tropical cyclone formation here varies widely from year to year, ranging from over twenty to one per year.
North Atlantic Basin: The most-studied of all tropical basins, it includes the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. If a low level circulation forms under this convection, it may develop into a tropical cyclone. Decaying frontal boundaries may occasionally stall over warm waters and produce lines of active convection. A warm-core tropical cyclone may result when one of these (on occasion) works down to the lower levels and produces deep convection.
Tropical upper tropospheric troughs, which are cold-core upper level lows. A similar phenomenon to tropical waves are West African disturbance lines, which are squally lines of convection that form over Africa and move into the Atlantic. Most tropical cyclones form from these. This often assists in the development of thunderstorms, which can develop into tropical cyclones.
Tropical waves, or easterly waves, which, as mentioned above, are westward moving areas of convergent winds. High wind shear can break apart the vertical structure of a tropical cyclone. Low vertical wind shear (change in wind speed or direction over height). (2004's Hurricane Ivan was the strongest storm to form closer than 10 degrees from the equator; it started forming at 9.7 degrees north.).
A distance of approximately 10 degrees or more from the equator, so that the Coriolis effect is strong enough to initiate the cyclone's rotation. This is most frequently provided by tropical waves—non-rotating areas of thunderstorms that move through tropical oceans. A pre-existing weather disturbance. Temperature in the atmosphere must decrease quickly with height, and the mid-troposphere must be relatively moist.
Upper-atmosphere conditions conducive to thunderstorm formation. The moisture in the air above the warm water is the energy source for tropical cyclones. Sea surface temperatures above 26.5 degrees Celsius (79.7 degrees Fahrenheit) to at least a depth of 50 meters (164 feet). From Urdu, Persian or Arabic ţūfān (طوفان) < Greek tuphōn (Τυφών).
The first record of the character 颱 appeared in 1685's edition of Summary of Taiwan 臺灣記略). (The Chinese term as 颱風 táifēng, and 台風 taifu in Japanese, has an independent origin traceable variously to 風颱, 風篩 or 風癡 hongthai, going back to Song 宋 (960-1278) and Yuan 元(1260-1341) dynasties.
