摘　　要：By using the data of 1949 – 2001 (53 years) of Tropical Cyclone (TC) Yearbooks, statistical analyses are performed to study the climatic features of TCs making landfall and then passing through lakes (hereafter referred to as "L-TCs") in China. Results show that L-TCs can sustain a long time over land and the intensity is very strong during the course of landfall. Lakes can noticeably slow down the reduction of TC intensity, 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 areas where the TC is active.By using the data of 1949 – 2001 （53 years） of Tropical Cyclone （TC） Yearbooks, statistical analyses are performed to study the climatic features of TCs making landfall and then passing through lakes （hereafter referred to as ＂L-TCs＂） in China.
