| 摘 要： | 利用NCEP再分析资料和上海台风研究所整编的热带气旋资料,研究了在太平洋年代际振荡(PDO)冷暖位相中西北太平洋热带气旋频数与太平洋海表温度(SST)年际相关的分布差异,以及500 hPa高度场对热带气旋频数和生成源地的影响.结果表明,在PDO冷位相时期,热带气旋频数与赤道东太平洋SST存在显著相关,副热带高压位置偏东...

| Abstract: | The distributions of the interannual teleconnections between the frequency of tropical cyclone over the western north Pacific and Pacific sea surface temperature(SST) are analyzed from cold phase to warm phase of the Pacific Decadal Oscillation(PDO) by using the NCEP reanalysis data and Shanghai Typhoon Institute data.The influence of 500 hPa height field is also analyzed.The change is characterized by the following: in cold PDO phase,the frequency of tropical cyclone and equatorial eastern Pacific SST is s... |
