Abstract
With the data from the Tropical Cyclone Yearbooks between 1970 and 2001, statistical analyseswere performed to study the climatic features of landfall TCs (noted as TCs hereafter) in China with particularattention focused on landfall frequency, locations, sustaining, decaying, transition, intensification and dissipationetc. The results indicate that the sustaining periods of TC over land are quite different for different landfall spots,and increased from Guangxi to Zhejiang. The most obvious decreasing of TC intensity occurs mainly within 12hours after landfall. The stronger a TC is,the more it decays. The areas over which TCs are dissipated can be inHeilongjiang, the northernmost, and Yunnan, the westernmost. Besides, Guangxi is an area with highdissipating rate and subject to TC dissipation as compared with the other coastal regions.
