Typhoon Ute is coming. What are the naming rules for typhoons?

This year'sNo. 1 1 Typhoon Yute (name origin: USA, name meaning: squall line) was generated in the northwest Pacific at 02: 00 on August 10, and intensified into a typhoon on June14. 12 landed on the eastern coast of Luzon Island in the Philippines at 03: 00, and weakened into a strong typhoon after landing. 12 entered the central and eastern South China Sea on 10, and weakened into a typhoon. It is predicted that starting from 13, it will bring obvious wind and rain weather to Hainan Province.

According to the monitoring of Hainan Provincial Meteorological Observatory, typhoon "Yute" No.11this year was located in the eastern part of the South China Sea about 920 kilometers southeast of Wenchang, Hainan at 3 pm on August 12. The maximum wind force near the center is 13, and the wind speed reaches 40 meters per second. The 7-level gale range has a radius of 280 kilometers, 10 gale range.

The Hainan Provincial Meteorological Observatory predicts that Ute will move to the west-northwest direction at a speed of about 25 kilometers per hour in one day, and its intensity will be strengthened. It will gradually approach the coast from the northeast of Hainan Island to the west of Guangdong, and will land on the above coast on 14.

Affected by it, from the night of 12 to the day of 15, there was heavy rain on cloudy days near zhongsha islands, with northerly winds112, gusts 13 and southerly winds of 9-3 during the day of 13. In the sea area near Xisha Islands, the northeast wind is 5-6, and the gust is 7. On 13, it increases to 7-8 during the day and the gust is 9. The southwest wind near Nansha Islands is 6-7, and the gust is 8; From Chengmai, Haikou to Lingshui, Hainan Island, the northeast wind is level 5, and on 13, the northerly wind turns to level 6-7 during the day, and the gust is level 8. At night, it gradually increased to10-1,and the gust 12, and the typhoon No.2 ball hanging in the coastal ports in the above areas remained unchanged. The sea surface from Beibu Gulf, Sanya and Ledong to Lingao in Hainan Island, the northeast wind is 5, the northerly wind 13 turns to 6-7 at night, and the gust is 8. During the day of 14, it gradually increased to 9- 10, and the gust was 1 1.

On land, rainfall increases gradually.

In addition, from the night of 13 to 14, there will be 8- 10 gale on the coastal land around Hainan Island from east to west.

Typhoon naming rules

number

The Pacific Northwest is the region with the most frequent typhoon activity in the world, with as many as six or seven landings in China every year. In the past, countries and regions concerned used different names to call tropical storms here, and the same typhoon often had several names. China is numbered by four codes according to the region and time of occurrence, with the first two digits being the year and the last two digits being the sequence number. The typhoon centers of the Asia-Pacific Regional Professional Meteorological Observatory under the World Meteorological Organization in Tokyo, Japan, are numbered in the order of east longitude 180 degrees and north of the equator. The Joint typhoon warning center, the Guam Navy of the United States, is named after the British and American countries, and Guam is also commonly used in international media reports. Some countries or regions have their own names for typhoons that affect this area. Nowadays, in order to avoid confusion of names, the Northwest Pacific and the South China Sea (the Northwest Pacific and the South China Sea refer to the Pacific and the South China Sea west of 180 degrees east longitude and north of the equator) adopt a unified tropical cyclone nomenclature. All members of the Typhoon Committee of the World Meteorological Organization (WMO) and relevant WMO members along the Pacific Northwest provided the names of the tropical cyclone nomenclature table.

The naming of tropical cyclones was discussed and approved by the Typhoon Committee of the World Meteorological Organization at its 3rd session 1, and the relevant operational procedures were implemented from 20001. The naming table * * * has 140 names from Cambodia, China, North Korea, China, China, Hong Kong, Japan, Laos, Macau, Malaysia, Micronesia (Federated States of), Philippines, South Korea, Thailand, the United States and Vietnam, and each member contributes 10 names.

Named tables are named in sequence and recycled.

The naming of tropical cyclones in the northwest Pacific and South China Sea has the following principles: each English name does not exceed 9 letters; Easy to pronounce; There is no bad meaning in the language of member States; Will not bring any difficulties to member States; Not the name of a commercial organization; The name chosen should be recognized by all Member States; The Chinese translation is determined by the China Meteorological Bureau, the Hong Kong Observatory and the Macau Geophysical and Meteorological Observatory through consultation. Chinese mainland proposed 10: anemone, Wukong, Yutu, Haiyan, Fengshen, Poseidon, Rhododendron, Dian Mu, Hippocampus and Begonia.

The Regional Specialized Meteorological Center (RSMC) of the World Meteorological Organization-Tokyo Typhoon Center is responsible for naming tropical cyclones reaching tropical storm level and above according to the naming table determined by the Typhoon Committee, and tropical cyclones are named in a predetermined order. Tropical cyclones keep their names unchanged throughout their life history; For tropical cyclones entering the northwest Pacific through the international international date line, the original name of the hurricane center in the central Pacific of the United States remains unchanged; For tropical cyclones that cross the international international date line from west to east, the name of Tokyo Typhoon Center will be maintained.

Members of the Typhoon Committee may apply to delete the name used by the tropical cyclone that caused particularly serious disasters from the list of names (the name becomes the exclusive name of the tropical cyclone that caused particularly serious disasters), or they may apply to delete the name for other reasons. The annual meeting of the Typhoon Committee will review the typhoon naming table, and the deleted names will be replaced by new names.
