摘要： 五十年代末到六十年代初许多气象工作者从环流的季节变化来研究我国的季节。高由禧等在研究东亚季风的基础上,对东亚季节划分作了比较系统的研究,揭示了东亚天气气候的许多重要规律。六十年代和七十年代以来,积累了许多对流层上层天气系统的研究资料,并开展了对青藏高原的作用,尤其是热力作用的系统研究,同时对我国雨带和雨季的特征也作了许多新的工作。因此有必要对东亚季节的划分问题重新进行分析。分析季节的变化是认识长期天气过程的基础,我们希望这项工作对认识东亚的天气气候规律有所裨益。

Abstract: In this paper,based on variation of atmospheric activity center in troposphereof East Asia and variation of the resultant wind fields of relative layers inperiods of deca-day,together with author’s recent analytic work about theinfluence of the ocean,continent and plateau to the temperature fields in EastAsia and the seasonal variation of the rain belts in China,we redivided thesynoptic climate seasons in East Asia as follows:Spring,from early of April to end of May or early of June;Summer,fromend of May or early of June to early of September;Autumn.from early of September to middle of October;Winter,from middle of October to early of April.And Summer was divided into five sections,as follows:1.End of May or early of June to first half of June;2.Second half of June to first deca-day of July;3.End of first deea-day of July to early of last deca-day of July;4.End of last deca-day of July to first half of August;5.Second half of August to early of September.
