摘要
Decadal variations of extreme tropical cyclones(TCs) influencing China were.investigated based on the tracks, landfall information,precipitation and wind data during 1949-2009.The extreme landfall date events are less in the 1970s and 2000s.The number of extreme events of maximum wind speed and minimum pressure near TC's center reached the highest in the 2000s.The extreme rain duration events had the highest frequence in the 1970s,and the extreme strong wind duration events had the maximum frequence in the 1980s.The number of stations whereat the extreme maximum daily precipitation or process precipitation is observed,is the largest in the 1960s,and the number of stations whereat daily maximum wind speed events are observed,is the largest in the 1980s.

The extreme landfall date events are less in the 1970s and 2000s. The number of extreme events of maximum wind speed and minimum pressure near TC＇s center reached the highest in the 2000s. The extreme rain duration events had the highest frequence in the 1970s, and the extreme strong wind duration events had the maximum frequence in the 1980s. The number of stations whereat the extreme maximum daily precipitation or process precipitation is observed, is the largest in the 1960s, and the number of stations whereat daily maximum wind speed events axe observed, is the largest in the 1980s.
