| 摘 要： | We statistically analyze the tropical typhoon forming in the South China Sea and use TC (Tropical
Cyclone) for short in the following) by typhoon yearbook. The typhoon quantity is very different in different
months and years. TC appears in all months except March, and the most TC quantity in a year is 11, the least is 1
and 6.2 on average. The most TC quantity in a month is 5 and the least is 0. TC lands most in August and no TC
lands on Chinese continent from December to the following April. The primary landing area is between Shantou
and Hainan Island. The sustaining period of TC is usually between 4 days to 7days, and the longest is 19 days.
Only 15% of the TC forming in the South China Sea can intensify to typhoon, and they all form in the ocean area
deeper than 150m. The South China Sea is the ocean area over which the TC occurs frequently.
