【摘要】 利用1949—2009年影响中国的热带气旋风雨资料以及登陆信息,研究影响热带气旋极端事件的年代际变化特征。结果表明:热带气旋登陆极端偏早或偏晚事件在1970和2000年代发生较少。热带气旋登陆强度(中心附近最大风力和最低气压)极端事件在2000年代发生频数最高。热带气旋降水影响时间极端事件在1970年代频数最多,大风影响时间极端事件在1980年代频数最多。日降水量和过程降水量的极值站数在1960年代最多,日最大风速极值站数在1980年代最多。更多还原

【Abstract】 Decadal variations of extreme characteristics of tropical cyclones(TC) influencing China were investigated based on the tracks,landfalling information,precipitation and wind data of the TCs in the period 1949-2009.The extreme landfalling date events had less frequency in the 1970s and the 2000s.The extreme maximum wind and minimum pressure events had the highest frequency in the 2000s.The extreme precipitation duration events had the highest frequency in the 1970s,and the extreme strong wind duration events had the maximum frequency in the 1980s.The number of stations whereat the extreme maximum daily precipitation or process precipitation were observed,was the largest in the 1960s,and the number of stations whereat daily maximum wind speed events were observed,was the largest in the 1980s.更多还原
