Di sebalik nama taufan
Oleh AZLINARIAH ABDULLAH (WARTAWAN UTUSAN)

KITA dihidangkan menerusi kaca televisyen dan paparan di akhbar dengan kesan malapetaka alam yang berlaku kepada dunia dalam dua tiga tahun kebelakangan ini. Kesannya itu, seperti hilang harta benda, orang tersayang dan sebagainya cukup menyentuh jiwa, walaupun di sini, kita dilindungi daripada bencana-bencana seperti itu.

Atas dasar ikatan kemanusiaan, kita turut terpanggil untuk 憈erlibat

Kenapa dulu2 org associatekan nama taufan ngan nama pompuan ek :hmm: diskriminasi tul, ingat kita ni cam taufan ke?

Syd

heheheh

pempuan bisa memusnahkan

piot

bila dengar cite pasal taufan ni...sedih dan takut...
tapi,bila dengar nama2 taufan...memang lawaklah....
macam2....cuma takde bin n binti jek...

Tropical cyclone
From Wikipedia,
(Redirected from Typhoon)


A tropical cyclone is a storm system fueled by the heat released when moist air rises and the water vapor in it condenses. The term describes the storm's origin in the tropics and its cyclonic nature, which means that its circulation is counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Tropical cyclones are distinguished from other cyclonic windstorms such as nor'easters, European windstorms, and polar lows by the heat mechanism that fuels them, which makes them "warm core" storm systems. Depending on their location and strength, there are various terms by which tropical cyclones are known, such as hurricane, typhoon, tropical storm, cyclonic storm, and tropical depression.

Tropical cyclones can produce extremely strong winds, tornadoes, torrential rain, high waves, and storm surges. They are born and sustained over large bodies of warm water and lose their strength over land, which is why coastal regions can receive much damage while inland regions are relatively safe from receiving strong winds. Heavy rains, however, can produce significant flooding inland, and storm surges can produce extensive coastal flooding up to 25 miles/40 km inland. Although their effects on human populations can be devastating, tropical cyclones also can have the beneficial effect of relieving drought conditions. They carry heat away from the tropics, an important mechanism of the global atmospheric circulation that maintains equilibrium in the Earth's troposphere.

Cyclone Catarina, a rare South Atlantic tropical cyclone viewed from the International Space Station on March 26, 2004


Naming

Brazilian meteorologists named the storm Catarina for its proximity to (and eventual landfall at) the state of Santa Catarina, although government forecasters initially denied that the storm, which clearly had an open eye and various other tropical morphologies, was a hurricane at all.

North American forecasters, however, surprised as they were, considered this a hurricane immediately upon the satellite-derived evidence. Since it had clear eyewall structure bounded by deep convective central dense overcast, well-defined spiral outer bands and outflow structure, warm water temperatures of 79癋 (26癈), little shear, a warm core low, and overall tropical characteristics, it was considered a hurricane by the National Hurricane Center in the United States.[2]

Though it is most commonly known as Catarina, all names for this storm are "unofficial", in that no World Meteorological Organization-affiliated meteorological agency that monitors hurricanes named it. (Tropical cyclone names are predetermined by an international committee of the World Meteorological Organization.)[3] It has also been unofficially called "Aldonça"[4], and the advisory names for it were "01T-ALPHA" from the United Kingdom's Met Office, and "50L-NONAME" from the United States' National Hurricane Center, which keeps it well outside normal designation, which start at 1L for named storms and use 90L to 99L for possible storms.

There is also no official naming convention for the meteorological term of tropical cyclones with winds of at least 74 mph (119 km/h) (i.e. hurricane, typhoon, cyclone) in the South Atlantic basin; however, because it was in the Southern Hemisphere, it is typically considered Cyclone Catarina, the predominant term for Southern Hemisphere tropical cyclones.

Typhoon Saomai

hree tropical cyclones at different stages of development. The weakest, on the left, demonstrates only the most basic circular shape. The storm at the top right, which is stronger, demonstrates spiral banding and increased centralization, while the storm in the lower right, the strongest, has developed an eye.

Storm history

Hurricane Katrina formed as Tropical Depression Twelve over the southeastern Bahamas on August 23, 2005 as the result of an interaction of a tropical wave and the remains of Tropical Depression Ten. The system was upgraded to tropical storm status on the morning of August 24 and at this point, the storm was given the name Katrina. The tropical storm continued to move towards Florida, and became a hurricane only two hours before it made landfall between Hallandale Beach and Aventura, Florida on the morning of August 25. The storm weakened over land, but it regained hurricane status about one hour after entering the Gulf of Mexico.[1]

When naming occurs

Storms reaching tropical storm strength are given names for several reasons: to eliminate confusion when there are multiple systems in any individual basin at the same time, to assist in recording insurance claims, to assist in warning people of the coming storm, and to further indicate that these are important storms that should not be ignored. These names are taken from lists which vary from region to region and are drafted a few years ahead of time. The lists are decided upon, depending on the regions, either by committees of the World Meteorological Organization (called primarily to discuss many other issues), or by national weather offices involved in the forecasting of the storms. Each year, the names of particularly destructive storms (if there are any) are "retired" and new names are chosen to take their place.

Naming schemes

In the North Atlantic and Northeastern Pacific regions, feminine and masculine names are alternated in alphabetic order during a given season. The gender of the season's first storm also alternates year to year. Six lists of names are prepared in advance, and each list is used once every six years. Five letters

Renaming of tropical cyclones

In most cases, a tropical cyclone retains its name throughout its life. However, a tropical cyclone may be renamed in several occasions.

   1. A tropical storm enters the southwestern Indian Ocean from the east

          In the southwestern Indian Ocean, M閠閛-France in R閡nion names a tropical storm once it crosses 90癊 from the east, even though it has been named. In this case, the Joint Typhoon Warning Center (JTWC) will put two names together with a hyphen. Examples include Cyclone Adeline-Juliet in early 2005 and Cyclone Bertie-Alvin in late 2005.

   2. A tropical storm crosses from the Atlantic into the Pacific, or vice versa

          It was the policy of National Hurricane Center (NHC) to rename a tropical storm which crossed from Atlantic into Pacific, or vice versa. Examples include Hurricane Cesar-Douglas in 1996 and Hurricane Joan-Miriam in 1988.[34] Should a tropical cyclone during its passage over Mexico or Central America maintain its area of low pressure without dissipation into the adjacent tropical cyclone basin, it retains its name. However, a new name is given if the original surface circulation dissipates.[35] Up to now, there has been no tropical cyclone retaining its name during the passage from the Northeast Pacific to the Atlantic basin, or vice versa, since the policy change in 2001.

   3. Uncertainties of the continuation

          When the remnants of a tropical cyclone redevelop, the redeveloping system will be treated as a new tropical cyclone if there are uncertainties of the continuation, even though the original system may contribute to the forming of the new system. One example is Tropical Depression 10-Tropical Depression 12 (which became Hurricane Katrina) from 2005.

   4. Human errors

          Sometimes, there may be human faults leading to the renaming of a tropical cyclone. This is especially true if the system is poorly organized or if it passes from the area of responsibility of one forecaster to another. Examples include Tropical Storm Ken-Lola in 1989[36] and Tropical Storm Upana-Chanchu in 2000[37]

History of tropical cyclone naming

For several hundred years after Europeans arrived in the West Indies, hurricanes there were named after the saint's day on which the storm struck. If a second storm struck on the same saint's day later, it would be referred to as segundo (Spanish for "the second"), as with Hurricane San Felipe Segundo.

The practice of giving storms people's names was introduced by Clement Lindley Wragge, an Anglo-Australian meteorologist at the end of the 19th century. He used female names, the names of politicians who had offended him, and names from history and mythology.[38][39] During World War II, tropical cyclones were given feminine names, mainly for the convenience of forecasters and in a somewhat ad hoc manner. In addition, George R. Stewart's 1941 novel Storm helped to popularize the concept of giving names to tropical cyclones.[40]

From 1950 through 1952, names from the Joint Army/Navy Phonetic Alphabet were used for storms in the North Atlantic.[41] The modern naming convention was in response to the need for unambiguous radio communications with ships and aircraft. As transportation traffic increased and meteorological observations improved in number and quality, several typhoons, hurricanes, or cyclones might have to be tracked at any given time. To help in their identification, the practice of systematically naming tropical storms and hurricanes was initiated in 1953 by the United States National Hurricane Center. Naming is now maintained by the World Meteorological Organization (WMO).

In keeping with the common English language practice of referring to named inanimate objects such as boats, trains, etc., using the female pronoun "she," names used were exclusively feminine.[citation needed] The first storm of the year was assigned a name beginning with the letter "A," the second with the letter "B," etc. Because tropical storms and hurricanes are often destructive, some considered this practice sexist. The WMO responded to these concerns in 1979 with the introduction of masculine names to the nomenclature. It was also in 1979 that the practice of preparing a list of names before the season began. The names are usually of English, French, or Spanish origin in the Atlantic basin, because these are the three predominant languages of the region that the storms typically affect. In the southern hemisphere, male names were given to cyclones starting in 1975.[39]

kite ingatkan derang namekan taufan atau pape jela berdasarkan name saintis yg discover taufan tuh. pestu tibe2 lak ade taufan durian plak. takkan ade org name durian kan. rupenye mmg dah ade listnye eh. taufan siti tade ke? aminah ke? nih seme name2 omputih je.. tak best la.

cam meteor.. derang amik name saintis yg discover meteor tu. cam dlm citer Deep Impact.

Gunner

fuh..gerun tgk gambar2 taufan dari  satelit tu...anehnya mcmane topan2 ni leh terbentuk ye..adakah ia boleh diramalkan bila2 ia akan terbentuk??musykil haku...

pokya

ade satu joke sbb ape taufan ni guna nama pompuan
it's wild and wet
lawak bodoh je ni hehe

alphawolf

Boleh...bila bermula musim taufan, ahli kajicuaca akan melihat suhu laut dikawasan pantai barat Afrika dan pantai barat Amerika Selatan. Suhu tinggi mungkin bermakna taufan buruk boleh berlaku...

Gunner

selalunya ditempat2 tersebut sahaje ke tempat diorang mengesan pembentukan topan2 nie?nasib baik di nusantara tidak berlaku topan2 yang dahsyat...

alphawolf

Tu tempat 'biasa' taufan lahir - di pantai Afrika ia akan bergerak ke Caribbean/Selatan Amerika. Kat Pasifik, dari luar pantai Amerika Selatan akan bergerak ke HK, Taiwan, Jepun atau Filipina...

Taufan juga boleh berlaku di Australia, Lautan Atlantik Selatan dan Lautan Hindi. Dan kalau tak salah, bencana alam terburuk dalam sejarah berlaku tahun 1970, bila Bangladesh dilanda siklon tropika dan membunuh kira-kira 1 juta orang.
