What is the name of the typhoon?

The internationally unified naming method of tropical cyclones for typhoons is that colleagues in neighboring countries and regions affected by tropical cyclones first make a naming table, and then recycle it 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 may request the World Meteorological Organization to remove their names. However, there are exceptions to the removal of typhoons. Some typhoons were deleted for "purely technical" reasons and retired purely on the basis of their names.

Extended data

A tropical cyclone whose intensity of tropical storm is higher than that generated in the northwest Pacific Ocean is called a typhoon. Tropical cyclone is a cyclone circulation weather system that occurs on the sea surface in tropical and subtropical areas, and it is one of the most destructive weather systems in geophysical environment. The volume of tropical cyclones is huge, ranging from 300-400 km to 1000-2000 km in diameter, with divergent coverage.

The substances involved are air and water vapor on the tropical ocean surface, and the latent heat contained in water vapor is its energy source. The change of tropical cyclone intensity is mainly affected by water vapor supply. In the environment with sufficient water vapor, the frequency of tropical cyclone generation is relatively high, and its development is strengthened rapidly. On the ocean surface with insufficient water vapor, the frequency of tropical cyclones is very low, and without them, there would be no development and enhancement.

Therefore, tropical cyclones are only produced in several regions of the earth. For example, tropical and subtropical oceans such as the Northeast Pacific Tropical, the Northwest Pacific Tropical, the Southwest Pacific, the Indian Ocean near the Bay of Bengal, the South Indian Ocean and the Northwest Atlantic Ocean are formed.

When tropical cyclones move to the lower temperature ocean surface, they will weaken and dissipate due to the decrease of water vapor supply, or lose the characteristics of tropical cyclones and turn into temperate cyclones. Tropical cyclones rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.

Strong winds, heavy rains and storm surges accompanying tropical cyclones may cause serious property losses or casualties; However, tropical cyclones are also an important part of atmospheric circulation, which can bring heat energy from tropical areas to middle and high latitudes.
