Abstract: The climatic features of the tropical cyclone (TC) influencing China have been analyzed by using the TC data from 1956 to 2000. The results show that there exist different features of the TC activities influencing China in different periods. In 1960's, there were relatively fewer TC influencing China and, then more TC affecting China in the following 1970 and 1980's, and another fewer TC period appears in 1990's. The central TC pressures are about 980~999 hPa, in which the landing TCs in east China are more intense than that in south China. Moreover, it is also found that there exist two closely correlated areas with high persistence between the annual TC numbers influencing China and the SST anomalies in the Pacific ocean, i.e. the western Pacific pool region(120~150°E, 10~20°N)with positive correlation and the central and eastern equatorial Pacific (180~90°W, 10 S~5°N) with negative correlation. The climatic features of the influencing TC in El Niño and La Niña years are also analyzed. In El Niño year fewer but more intense TCs influence China, but in La Niña year more but weaker TCs affect China. The Patterns of the SST anomalies in the Pacific ocean in more TC years and fewer TC years are similar to those in La Niña years and El Niño years.
