赤道东太平洋海温对东亚～西北太平洋温带气旋的影响

THE ACTIVITY FEATURE OF THE EXTRAROPICAL CYCLONES FROM EASTERN ASIA TO WESTERN PACIFIC AND RELATIONS BETWEEN THE EQUATORIAL PACIFIC SST AND THE EXTRATROPICAL CYCLONES

本文分析了东亚～西北太平洋较强温带气旋的气候特征及其与赤道东太平洋海温的关系。得出，厄尔尼诺年或厄尔尼诺持续年，较强温带气旋偏多的对应关系占优势。但当副热带高压偏强时，则较强温带气旋偏少。

In this paper, the activity feature of extratropical cyclone from eastern ASIA to westernPacific and relations between the equatorial Pacific SST and the extratropical cyclones wereanalysed. The results obtaind that the stronger extratropical cyclones were more in yearsof EL Nino and continued years of EL Nino. But it were less when the subtropical ridgeof the western Pacific was stronger.
