The analysis of typhoons landing in China since 1949 shows that the typhoons landing in China have shown the following main characteristics for more than half a century.
The Central Meteorological Observatory numbers the tropical cyclones with the maximum average wind force at the bottom near the center of the Pacific Ocean and the South China Sea that occur or enter the Pacific Ocean and the South China Sea to the north of the equator and the west of 180 ° east longitude every year, which are ≥ 8.
The formation of a typhoon eye is due to the wind in the typhoon blowing counterclockwise, which makes the central air rotate. The centrifugal force caused by the rotation is balanced against the wind blowing into the center, so that the strong wind can no longer converge to the center. Therefore, there is no wind within tens of kilometers of the typhoon center, and there is air sinking and warming,Cause clouds to dissipate and rain to become typhoon eyes.
