利用1949~2001年热带气旋年鉴资料,对53年登陆我国并经过内陆湖泊的热带气旋特征进行统计分析。结果表明:登陆过湖泊热带气旋在陆上维持时间长,登陆时强度较强;湖泊地带能延缓登陆TC强度的衰减;热带气旋经过内陆湖泊时大多表现为中心气压维持不变或降低,风速增大;长江中游地区是登陆过湖泊热带气旋消失数最多的区域。
By using 53-year tropical cyclone(TC) Yearbooks data from 1949 to 2001, statistical analyses are performed to study the climatic features of landing TCs through lakes in China. Results show that those TCs can sustain long time inland and the intensity is very strong during the landfall. The lake can noticeably reduce decay due to landfall, with the minimum pressure mostly maintained or decreased and the maximum velocity increased. The middle reach of the Yangtze River has the biggest TC dissipating rate as compared with the other TC activity areas.
