| 摘 要： | With the data from the Tropical Cyclone Yearbooks between 1970 and 2001, statistical analyses
were performed to study the climatic features of landfall TCs (noted as TCs hereafter) in China with particular
attention focused on landfall frequency, locations, sustaining, decaying, transition, intensification and
dissipation etc. 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 12 hours after landfall. The stronger a TC is，the more it decays. The areas over which TCs are dissipated
can be in Heilongjiang, the northernmost, and Yunnan, the westernmost. Besides, Guangxi is an area with high
dissipating rate and subject to TC dissipation as compared with the other coastal regions.
