东亚温带气旋及其长期预报（二）──预报应用分析

EXTRATROPICAL CYCLONE AND IT'S LONG RANGE FORECAST IN EASTERN ASIA──AN ANALYSIS OF FORECASTING APPLICATION

本文以赤道东太平洋海温作为主导因子，分析其与东亚温带气旋的关系．得出：高海温多气旋、低海温少气旋的对应关系较为明显．并进一步对不符合这种主要关系的年份从环流型、下垫面海温等作了分类鉴别分析．

In this paper,the SST of equatorial eastern pacific being dominant factor.the relationship betweens the SST and extratropical cyclone of Eastern Asia was analyzed. It is found that the higher the SST the more the extratropical cyclone and vice versa, For those years when the mentioned relation is not hold,a type analysis for the cyclones is performed from circulation pattern and SST on underlying surface.
