How to name a typhoon?
Typhoon is a strong thermal cyclone (with low central pressure) formed on the vast tropical ocean surface. In terms of causes, typhoons and hurricanes have the same causes. They are all tropical cyclones developed on the basis of tropical depression. However, not all tropical cyclones can develop into typhoons or hurricanes. Strictly speaking, only tropical cyclones with the maximum wind force of 12 or above near the center of tropical cyclones are called typhoons or hurricanes. Typhoon and hurricane are the strongest tropical cyclones, but they have different names because of different sea areas. They are called hurricanes in the Indian Ocean and the Atlantic Ocean. Only the Pacific Northwest is called a typhoon. The storms brought by typhoons often cause serious meteorological disasters. People named typhoons in order to forecast, study and distinguish them in different periods.
How is a typhoon named? The naming of typhoon consists of two parts: number and name.
The number of typhoons is also the number of tropical cyclones. People want to number tropical cyclones, on the one hand, because a tropical cyclone often lasts for more than a week, and several tropical cyclones may appear in the ocean at the same time. With the serial number, there will be no confusion; On the other hand, the naming, definition, classification method and determination of the center position of tropical cyclones are different in different countries and methods, even in the same country, they are not exactly the same among different meteorological stations, which often leads to various misunderstandings and confusion in use.
Starting from 1959, China began to number the tropical cyclones (tropical storms and above) that occur or enter the Pacific Ocean and South China Sea north of the equator and west of 180 degrees east longitude every year according to the sequence of their occurrence. Offshore tropical cyclone. In the case of clear cloud structure and circulation, as long as the maximum average wind force near the center is above 7, it is also numbered. The serial number consists of four digits. The first two digits indicate the year. The last two digits are the serial numbers of tropical cyclones above storm level in that year. For example, last year's typhoon 13? Rhododendron? Its number is O3 13. It represents 13 tropical cyclone above storm level in 2003. Tropical depression and tropical disturbance are not numbered.
At the beginning of the 20th century, people began to name typhoons. It is said that the first person to name a typhoon was an Australian forecaster in the early 20th century. He named tropical cyclones as political figures he didn't like, so that meteorologists could call them publicly. In the northwest Pacific, the official naming of typhoons began with 1945. At first, only female names were used. Later, it is said that due to the opposition of feminists, starting from 1979, men's names and women's names were used alternately. Until 1997, 1 65438+1October 25th to 65438+February1,the 30th meeting of the Typhoon Committee of the World Meteorological Organization (WMO) held in Hong Kong decided that tropical cyclones in the northwest Pacific Ocean and the South China Sea should be named in Asian style, and it was decided that tropical cyclones in the year of 2000 should be named in the Asian style. The new naming method is to make a naming table in advance and then reuse it year after year in sequence. The naming table * * * has 140 names and is provided by 14 member countries and regions in the Asia-Pacific region to which WMO belongs, such as Cambodia, China, North Korea, Hong Kong, Japan, Laos, Macau, Malaysia, Micronesia, the Philippines, South Korea, Thailand, the United States and Vietnam. Each country or region provides 65,438+00 names. The 140 names are divided into 10 groups, and each group has 14 names. Arranged in alphabetical order according to the English names of member countries, and recycled in turn. At the same time, the original number of tropical cyclones remains.
Browse the typhoon naming table. Names are rarely used, mostly animals, plants, food and so on. There are also some names that are adjectives or beautiful legends, such as Yutu and Wukong. ? Rhododendron? The name was provided by China. Is the familiar azalea: landing in China some time ago? Korovan It was provided by Cambodia. It's the name of a tree: Morakot? It is provided by Thailand, which means jade: Ibudu? It is a name provided by the Philippines, which means chimney or water pipe, which discharges rainwater from the roof into the ditch.
Under normal circumstances, the pre-established named list is recycled year after year in sequence, but under special circumstances, the named list will also be adjusted. For example, when a typhoon is notorious for causing particularly serious disasters or casualties and becomes a well-known typhoon, in order to prevent it from having the same name as other typhoons, the name will be deleted from the current naming list and replaced with a new name. The latest revision of the typhoon nomenclature table was made at the 33rd meeting of the Typhoon Committee in 2000, and the table has been implemented since June 65438+ 10/.
