Typhoon nomenclature is also the naming system of tropical cyclones in the northwest Pacific and South China Sea, which can also be called the naming system of tropical cyclones. Typhoon refers to the first-class tropical cyclone in the northwest Pacific Ocean and the South China Sea, and is often mistaken for another name for tropical cyclone. The internationally unified nomenclature of tropical cyclones is a nomenclature table first formulated by colleagues from neighboring countries and regions affected by tropical cyclones, and then recycled year after year in sequence. The naming table first gives English names, and each member country can translate the names into local languages according to pronunciation or meaning. When a tropical cyclone name is used, causing heavy losses to one or more member countries, the name will be permanently deleted and stopped. Member States that have suffered losses can request WMO to delete their names.

Naming method

The naming table * * * has a total of 140 names, which are provided by the Asia-Pacific region 14 member countries and regions of the World Meteorological Organization, namely Cambodia, Chinese mainland, North Korea, China, Hong Kong, Japan, Laos, China, Macau, Malaysia, Micronesia, the Philippines, South Korea, Thailand, the United States and Vietnam for convenience.

14 members put forward 140 typhoon names, and each country and region put forward 10 names.

China proposed 10: Dragon King (later replaced by anemone), Wukong, Yutu, Haiyan, Fengshen, Poseidon, Rhododendron, Dian Mu, Hippocampus and Begonia.

Interestingly, the names of typhoons in the western Pacific used internationally still have few meanings of disaster, and most of them have elegant and peaceful meanings, such as jasmine, rose, pearl, lotus and colorful clouds. This seems to be out of harmony with the typhoon disaster. This is because if a typhoon comes, it can effectively alleviate the local drought and bring enough precipitation. Under normal circumstances, the name of a typhoon is extremely pleasant to listen to.

If a tropical cyclone has caused particularly serious losses to members of the Typhoon Committee, the member may apply to delete the name used by the tropical cyclone from the name list, and give the tropical cyclone a permanent (permanent) name, and other tropical cyclones (typhoons) will no longer use the name. In this way, you need to add a new name to the naming table.

Naming use

Typhoon Yunna is under the responsibility of Tokyo Regional Professional Meteorological Center of Japan Meteorological Agency. When the Japan Meteorological Agency determines the tropical cyclone in the northwest Pacific or South China Sea as the intensity of tropical storm, it will give it a name according to the list and give it a four-digit number. The first two digits of the number are the year, and the last two digits are the order of tropical storms in that year. For example, Tropical Storm No.4 in 0704 and 07.

According to the regulations, a tropical cyclone's name will remain unchanged throughout its life cycle, whether it is strengthened or weakened. For example, tropical storm 0704, severe tropical storm and typhoon are all called "Manyi" in English and "Wan Yi" in Chinese. In order to avoid unnecessary confusion caused by multiple translators, the Central Meteorological Observatory in China, the Hong Kong Observatory and the Geophysical and Meteorological Observatory in Macau, China decided on a unified set of Chinese translations.

Under normal circumstances, the pre-made naming list is recycled year after year in sequence, but under special circumstances, the naming list will also be adjusted. For example, when a typhoon causes particularly serious disasters or casualties and becomes notorious, it becomes a well-known typhoon. In order to prevent it from having the same name as other typhoons, members of the Typhoon Committee may apply to delete the name from the name list, that is, the name will be given to the tropical cyclone forever, and other tropical cyclones will no longer use the name, such as "Yunna". When the name of a typhoon is deleted from the name list, the Typhoon Committee will supplement the name of a tropical cyclone according to the suggestions of relevant members.

From June 5438+1 October1in 2000, when the China Central Meteorological Observatory issued the tropical cyclone warning, it used not only the tropical cyclone number, but also the tropical cyclone name. Previously, China has been using tropical cyclone numbering method.

Folding retirement principle

Typhoons are often named after "tenderness". I hope the damage caused by typhoons will be less. However, the World Typhoon Committee stipulates that once a typhoon causes heavy losses to life and property, the name will be permanently occupied, and the name will be deleted from the name list, and the vacant name will be re-recommended by the original providing country or region.

For example, Typhoon Yunna means "Hello", but according to statistics, Typhoon Yunna caused 164 deaths and 24 people were missing in Zhejiang, resulting in direct economic losses of181280 million yuan. Permanently deleted from the international typhoon naming sequence.

In 2005, the name of "Dragon King" was on the typhoon 19, which wreaked havoc all the way and brought great threat to the local area. According to the data provided by the China Meteorological Bureau, the arrival of the Dragon King brought heavy precipitation to the local area. The hourly precipitation in Fuzhou exceeded the historical extreme value, exceeding 152 mm, which was the most serious impact of typhoons over the years. Because of its arrival, Fujian's economic loss was 7.478 billion yuan, resulting in nearly 100 deaths. Therefore, the International Typhoon Committee decided to delete the typhoon name "Dragon King" in China from the list of names, which was the first typhoon name "retired" provided by Chinese mainland.
