The yearbooks of typhoon are used to statistically analyze tropical cyclones in the South China Sea (Tropical cyclones of South China Sea here mean those formed in South China Sea, to be abbreviated as TC in the following text).TC quantity changes greatly month by month and year by year. Except for March, TC appears in all the other months. There are 11 TCs forming at most and 1 TC at least annually. There are five TCs at most and zero at least in terms of monthly formation. The time TC makes the most landfall is August, and from December to the following April no TC lands in China mainland. Landfalls mainly occur between Shantou and Hainan Island. TC lasts for 4-7 days generally and 19 days for the longest duration. About 15% of the TCs in the South China Sea intensify into typhoons, and all of them concentrate in the sea area where the depth of water is over 150 meters. The South China Sea is the area where TC happens frequently and also has a fairly large number.
