摘要
本文主要係利用長年候平均之台灣各地雨量及溫度資料，以分析台灣天氣變化之自然季節。發現就雨量變化言，「冬雨」（季風雨）、「春雨」、「梅雨」、「颱風雨」及「秋雨」，在台灣均有出現。但由於中央山脈之存在，而使台灣各區之雨制各有不同。最著者，台灣西部及南部僅有梅雨與颱風雨（含局部對流雨），冬半年屬乾季。東北部則上述五雨季均有存在，惟以秋雨與冬雨為最著。台灣各區雨期分佈及出現時間均經作出。就溫度言，台灣全區均甚一致，計可分為「前冬」、「後冬」、「春季」、「初夏」（或梅雨季）、「夏季」及「秋季」等六季。各季出現之時間及其候溫分佈特徵，均經作出。另外，台灣區域之風場季節變化，氣壓變化、雨量分佈之區域及季節變化特徵等，亦經作出。藉供長期預報之基本參考資料。

In this paper the natural seasons of the weather in Taiwan are classified according to the pented rainfall and temperature recorded from 1941 to 1979. As far as the pented rainfall is concerned five rain seasons can be identified, i.e., winter rain season, spring rain season, plum rain season, typhoon rain season and autumn rain season. In the northeastern Taiwan all five rainfall seasons are evident. In the southern and western Taiwan, however, only plum rain season and typhoon rain season are witnessed. Regarding the pented temperature, six seasons can be identified, i.e., early winter, late winter, spring, earIy summer, summer and autumn. The occurrence duration and typicaI temperature variation of five seasons are worked out. In addition, seasonaI variations in wind and pressure fields in the Taiwan area are also discussed.
