摘要
利用1949-2003年资料,统计了影响和登陆海南热带气旋频数的时空分布特征、初、终期分布,并探讨了ENSO事件对海南省热带气旋的影响和2004年无热带气旋影响海南的原因。指出ENSO事件与海南省热带气旋活动具有显著的相关性, 暖事件年有利于影响和登陆热带气旋偏少、初旋偏晚,冷事件年则相反。但ENSO 事件与终旋日期相关不显著。
Base on the tropic cyclone data from 1949 to 2003, the spatial-temporal distribution features of influencing and landing tropic cyclone（TC） numbers in Hainan Province, temporal distribution of the first and the last influencing TC to Hainan are analyzed. Furthermore, the relationship between ENSO and the influencing TC to Hainan, and the reasons that no TC influences Hainan in 2004 are investigated. The main results are as follows. （1） Correlation between ENSO and activity of influencing TC to Hainan is significant. （2） Influencing and landing TC to Hainan are getting less and the first influencing TC to Hainan is getting later in warm SSTa event, and vice versa. （3） Correlation between ENSO and the last influencing TC to Hainan is not significant.
