| 摘 要： | 本文从１９５３～１９８４年的３２年中挑选出７个热带气旋偏多年和７个偏少年，分析了与它们同期和前期的副热带高压、西风带纬向环流、北半球极涡以及赤道东太平洋海温、北极海冰的差异，发现其中的许多因子与热带气旋频数有很好的相关性，并指出在热带气旋年际变化这一时间尺度上，海洋因子的影响显得更重要。

| Abstract: | e have chosen seven overproduced years of tropical cyclones and the less-produced yearsfrom 1953 through 1984. The difference of tropical cyclones and subtropical high index, westerly belt zonal circulation index, Northern Hemisphere POlar vortex index and the Eastern equatorial pacific SST in the corresPOnding period and previous seasons is analysed. It is found thatmany factors are well corrlated with the frequency of tropical cyclones. It is POinted out thatthe influence of ocean factors is more imPOrtant for the interannual change of tropical cyclones. |
