In order to distinguish tropical cyclones, it is necessary to give them a separate name. Tropical cyclones are initially distinguished according to their location (mainly the latitude and longitude of their centers), which is quite troublesome and often unsatisfactory. Until the beginning of19th century, some Spanish-speaking Caribbean islands named hurricanes according to the calendar time when they landed. For example, three hurricanes hit Puerto Rico: Santa Ana on July 26th, 1825, san felipe on September 3rd, 1876 and 1928. It is reported that at the end of 19, Australian forecaster Clemen Langer named tropical cyclones after politicians he hated. Later, the military department named tropical cyclones in alphabetical order of English words (ABLE, BAKER, CHARLIE, etc. During World War II, Americans named tropical cyclones after women. At the end of 1970s, at the request of American feminist movement, the naming list was expanded to be named after men and women. In oral and written communication, especially in alarm, people gradually accept the advantages of using named tables. The name should be short, popular and easy to remember, so as to convey information to millions of people in tropical cyclone threat areas and avoid confusion when the same area is affected by more than one tropical cyclone at the same time. This practice was soon widely adopted in the western hemisphere. In 1970s, the naming system was used in all tropical cyclone-prone areas. After the end of 1970s, under the coordination of the Regional Tropical Cyclone Committee of the World Meteorological Organization, the naming of tropical cyclones went international. In most areas, the nomenclature of tropical cyclones (male and female names are usually used alternately) is formulated by the tropical cyclone committee in this area, and the more important task of the tropical cyclone committee is to promote and coordinate the tropical cyclone disaster reduction actions in this area. Specific practices vary from region to region. Designated meteorological centers are usually responsible for naming tropical cyclones alphabetically. Some regional naming tables are recycled, some regions often make new naming tables, and some regional naming tables are used from scratch after use. If a tropical cyclone is notorious, such as causing serious casualties or huge property losses, the name of the tropical cyclone should be deleted from the name list and replaced with another name of the same sex with the same initials. In some areas, tropical cyclones are named with four digits, the first two digits are the year, and the last two digits are the serial numbers of tropical cyclones in that year, and some have added geographical indications. For example, the tropical storm 1 in the Bay of Bengal in 0 was named BOB 9 109(BOB is the abbreviation of English Bay of Bengal). 1990 Typhoon No.25 was named 9025. Some countries have developed their own nomenclature, for example, the United States has developed a nomenclature for the Northwest Pacific and the North Central Pacific, and the Philippines has also developed a nomenclature for typhoons in the Northwest Pacific. The name of typhoon in the northwest Pacific used by joint typhoon warning center in Guam is often adopted by other countries in the region. Most members of the Typhoon Committee come from countries and regions affected by typhoons. For many years, the Typhoon Committee has set up a system for numbering typhoons, namely the Typhoon Center, namely the Tokyo Professional Meteorological Center, which is responsible for numbering tropical cyclones that reach the intensity of tropical storms. According to the resolution of the 3rd 1 meeting of the Typhoon Committee, a new tropical cyclone naming method was implemented from 65438+ 10/day in 2000. This method will be used in the communiqué issued by members of the Typhoon Committee to the international community. Members also use it to issue tropical cyclone warnings in local languages. The Typhoon Committee will continue to use tropical cyclone numbers. China has always adopted the numbering method of tropical cyclones, and numbered the tropical cyclones that occurred near the center of the northwest Pacific Ocean and the South China Sea, west of east longitude 180 degrees and north of the equator according to the sequence of their generation. For example, tropical storm 9608 was the eighth tropical cyclone generated in the above-mentioned sea area in 1996. When it develops into a strong tropical storm, it is called a strong tropical storm 9608. When it continues to develop into a typhoon, it is called a typhoon 9608. Of course, when it decays into a tropical storm, it is also called a tropical storm 9608. When a tropical cyclone weakens into a tropical depression or degenerates into an extratropical cyclone, the numbering will stop. From June 5438+1 October1day, 2000, when the Central Meteorological Observatory issued the tropical cyclone warning, the tropical cyclone numbers and names continued to be used. Tropical Cyclone Naming in the Northwest Pacific and South China Sea1997165438+1The 30th meeting of the Typhoon Committee held in Hongkong, China from October 25th to February 0th decided to study the proposal of naming tropical cyclones in the Northwest Pacific and South China Sea with Asian style, and appointed the Typhoon Research Coordination Group (TRCG) to study the implementation details. After a year's efforts, TRCG put forward the suggestion of naming tropical cyclones in the northwest Pacific and South China Sea. 1998 12 1 After a heated discussion, the Typhoon Committee 3 1 meeting in Manila, Philippines, agreed to the naming scheme of tropical cyclones in the northwest Pacific Ocean and the South China Sea proposed by TRCG, and decided to implement a new naming method for tropical cyclones from 1 in 2000. The Typhoon Committee naming list * * * has a total of 140 names, provided by Cambodia, China, North Korea, China, Hong Kong, China, Macau, China, Japan, Laos, Malaysia, Micronesia (Federated States of), Philippines, South Korea, Thailand, the United States and Vietnam in the Asia-Pacific region. The naming table of the Typhoon Committee will be used for forecasts, warnings and announcements issued to the international aviation and navigation community through the international media, and also for members to issue tropical cyclone warnings in local languages. This will help people to be more alert to the coming tropical cyclone and increase the effectiveness of warning. The Typhoon Committee will continue to use tropical cyclone numbers. 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. From June 5438+1 October1day, 2000, when the Central Meteorological Observatory issued the tropical cyclone warning, the tropical cyclone numbers and names continued to be used. Tropical cyclone 1 in 2000 was named "Davi" and was provided by Cambodia.
