摘　　要：利用1949～2001年西北太平洋热带气旋基本资料,对登陆我国热带气旋活动的气候特征进行了分析。结果表明,登陆我国的热带气旋频数存在显著的月际、年际和年代际差异,具有明显的时间日变化特征。同时指出,登陆我国热带气旋的频数与长江中下游地区梅雨量可能存在一定关系。此外,通过对在不同纬度带登陆的热带气旋进行统计分析发现,热带气旋所登陆的纬度带不同,其维持时间、衰减速度存在明显差异。By using the Northwest Pacific tropical cyclone data in the past 53 years from 1949 to 2001, the climatic features of the landing tropical cyclones in China are analyzed. The results show that the frequencies of the landing tropical cyclones in China present the obvious intermonth, interannual and interdieadal differences and the daily variation is also significant. It is also indicated that the relationship between the rainfall of Meiyu in the middle and lower reaches of the Yangtze River and the frequencies of the landing tropical cyclones maybe exist. In addition, the tropical cyclones at the different latitudes are statistically analyzed and the result shows that the maintaining time and the decreasing speed of the landing tropical cyclones are different when the latitude zones where the tropical cyclones land are different.
