What is the basis for the meteorological department to name the typhoon? V 30

The typhoon nomenclature method is a nomenclature that is developed in advance and then reused in a sequential cycle year after year. So what is the basis for the naming of typhoons? For those who don't know, let's take a look at the basis for the naming of typhoons.

On average, there are about 80 tropical cyclones in the world every year, of which about 28 tropical cyclones are formed in the northwest Pacific and the South China Sea every year. In order to make it easier to distinguish and remember, so that the early warning and defense of typhoons can be done well, it is necessary to give the typhoon a name.

The Northwest Pacific region is the region with the most frequent tropical cyclone activity in the world, except for the Gulf of Mexico, the Caribbean Sea and the North Atlantic region where the United States is located (the United States calls tropical cyclones hurricanes, and when they reach a certain intensity, they are called Category 1 hurricanes, and as tropical cyclones intensify, they are called Category 2 hurricanes or higher), and there are up to a dozen of them making landfall in China every year.

Before the international naming convention, the relevant countries and regions had different names for the tropical storms that infested the area, and the same typhoon often had several names. In China, according to the area and time of its occurrence, the first two digits are the year, and the last two digits are the sequence number. The typhoon centres of the Regional Meteorological Observatory for Asia and the Pacific of the World Meteorological Organization (WMO) in Tokyo, Japan, are numbered in the order of their entry into 180 degrees east longitude and north of the equator.

The U.S. Navy Joint Typhoon Warning Center is named after people in Britain and the United States, and international media also commonly use the name ** in their reports. There are also countries or regions that have their own names for typhoons that affect their regions.

People have been naming typhoons since the early 20th century, when it is said that the first time to name a typhoon was the early 20th century Australian forecaster Klimmenlange, who named the tropical cyclone after a politician he didn't like, so that meteorologists could openly jokingly call it.

In the Northwest Pacific, the official name of the typhoon began in 1945, and at first only the name of a woman was used, and it is said that since 1979, due to opposition from feminists, the name of a man and a woman have been used interchangeably.

In order to avoid confusion in the names, the 30th meeting of the Typhoon Committee of the World Meteorological Organization (WMO), held in Hong Kong from 25 November to 1 December 1997, decided that tropical cyclones in the north-western Pacific and the South China Sea should be named in an Asian style, and that a new nomenclature would be used from 1 January 2000.

Hello dear, <>

<> I am a Q&A expert on life Tong Tong: According to the naming rules of the International Meteorological Organization, the name of a typhoon is composed of the name of the surface system and the name of the circulation system. 1.

Typhoon names are based on their morphology. Typhoon names are based on their morphology. The morphology of typhoons is mainly divided into three categories, namely typhoons, tornadoes, and cyclones.

2.The name of the typhoon is based on its intensity. Typhoon names are given based on their intensity.

The typhoon is divided into five levels of intensity, from weak to strong: tropical depression, Vibi's tropical medium, tropical high, ultratropical high, and ultratropical depression. 3.

Typhoon names are given based on the time of their outbreak. Typhoon names are given based on the time of their outbreak. At present, there are two main typhoon nomenclature conventions used internationally:

The first is the World Meteorological Convention formulated by the United Nations Meteorological Organization in 1947, and the second is the 1981 Geophysical Oceanographic Typhoon Nomenclature jointly formulated by the United Nations Meteorological Organization and the International Oceanographic Society in 1982. <
