How is a typhoon named?

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 tropical cyclones (tropical storms and above) that occur or enter the Pacific Ocean and the South China Sea north of the equator and west of the 180 meridian every year in order of 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 Du Fu (13) numbered O3 13. , indicating the tropical cyclone with storm level 13 or above that occurred 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. There are 140 names in the naming list, which are provided by 14 member countries and regions in the Asia-Pacific region, such as Cambodia, China, North Korea, China, Hong Kong, Japan, Laos, China, 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. The name "Rhododendron" was provided by China, which is the familiar Rhododendron: "Korowang" that landed in China a while ago was provided by Cambodia, which is the name of a tree: "Morak" was provided by Thailand, which means jade; "Ibudu" is a name provided by the Philippines, which means chimney or water pipe to discharge 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/.

According to the forecast of the Provincial Meteorological Observatory, during the "Eleventh" Golden Week, the weather in our province is still dominated by subtropical high control. In the next three days, Hangzhou will still be mainly sunny to cloudy, with the highest temperature of 3 1-33℃ and the lowest temperature of 22-24℃, and the weather will be relatively stable.

There may be a weak rain in the middle of the long holiday.

Typhoon David has just ravaged Hainan, Guangdong and Guangxi. Typhoon Kloc-0/9 was born this year, and now more and more energy is accumulated at sea. According to the typhoon warning issued by the Central Meteorological Observatory, this year's No.0519 typhoon Longwang was located at 22.4 degrees north latitude and 0/36.8 degrees east longitude at 4/4 yesterday, with a central air pressure of 940 hectopascals, a maximum wind speed of 50 meters per second near the center, a moving speed of 10 km/h and a seven-level gale circle radius of 30.

The meteorological department predicts that the subtropical high will temporarily withdraw eastward from 2 to 3 October at 65438+/KLOC-0. Due to the influence of the weak cold air in the westerly belt and the typhoon trough top in the westbound direction of "Wang Long", there will be a weak precipitation process in our province, which is dominated by shower weather and lasts for a short time, so it should not affect everyone's travel pleasure. Four days later, the subtropical high once again strengthened its westward extension, which brought good weather for a long time in our province and will draw a satisfactory full stop for the Golden Week.

However, this is only a forecast based on the current weather conditions. According to meteorologists, according to the general law, typhoons in autumn are mostly southerly, westbound or northeast, and it is extremely rare for 65438+ 10 to affect our province. Since the founding of the People's Republic of China, only Typhoon No.6 126 landed in Sanmen of our province on June 4 10. Therefore, the typhoon "Dragon King" which has been heading west is most likely to land in southern Fujian after passing through southern Taiwan Province Province.

However, due to the variable of typhoon movement, and the fact that "Dragon King" is now moving very slowly and far away from land, it is still unknown whether it will land in China's coastal areas in the next few days, and the meteorological department is closely monitoring it.

The return of the "Dragon King" does not necessarily bring storms.

It is reported that the name of the typhoon "Dragon King" was named by Chinese mainland. Although it is a symbol of the rain god, it does not necessarily bring the threat of wind and rain. Before the first typhoon named "Dragon King" passed through Taiwan Province Province in 2000, even a typhoon warning at sea was not issued. This is the second typhoon named "Dragon King".

Besides the Dragon King, typhoons named by China include Wukong, Yutu, Haiyan, Fengshen, Poseidon, Du Fu, Dian Mu, Haima and Haitang. However, if a typhoon has caused particularly serious losses to human beings, its name may be permanently deleted from the list of typhoon names to avoid confusion caused by its popularity. For example, Yunna, which brought serious disasters to our province last year, was recorded as the proper name of the typhoon that caused major disasters in the history of typhoon meteorology in the world, and withdrew from the tropical cyclone nomenclature table.

Morning News (Reporter Zhu) At 2 o'clock yesterday afternoon, this year's No.9 typhoon "Dragon King" was located at 2 1.7 degrees north latitude and 140. 1 degree east longitude, which is 2,406 kilometers east of Quanzhou, with a speed of 15.

It seems that where the "Dragon King" went on holiday affected many people's holiday mood.

The Dragon King is walking very slowly now. Will the typhoon periphery affect Fujian during the National Day holiday? Experts are still paying close attention to its trend. I hope the "Dragon King" will turn quickly, so as not to cause any influence. During the National Day this year, do a good job in preventing typhoons and cold air.

Besides the Dragon King, there are other typhoon names named by China, such as Wukong, Yutu, Haiyan, Fengshen, Poseidon, Rhododendron, Dian Mu, Haima and Haitang. There was a dragon king before, and then Wukong and Poseidon, the wind god, came to help. People also gradually feel that these interesting names are not the true face of typhoons.

Experts from Quanzhou Meteorological Network said that the typhoon was terrible, and its devastating and overwhelming destructive power showed us the strength of nature and the fragility of human beings. Although we can't change it, we can keep track of its whereabouts for a rainy day.

This year'sNo. 18 typhoon "David" has begun to use and spread the name of the past typhoon, and "Dragon King" is the second. It is understood that if a typhoon causes particularly serious losses to human beings, its name may be permanently deleted from the list of typhoon names, so as to avoid confusion caused by its "popularity", just like "Yunna", which brought harm to Zhejiang last year, is a typhoon that caused major disasters.

After+10 in early June of 5438, the typhoon season in Quanzhou has come to an end. The late typhoon "Nanmadu" in June 5438+February last year was the latest typhoon in Quanzhou history.
