摘要
一、引言 高氣压系統的生成、發展和移動不僅是理論氣象学上和天氣学上的重要問題,而且也是做好天氣預報的重要關鍵之一。对东亞來說,如何預報西伯利亚以及歐洲等地冷高压的活動过程,是預報員在預報工作中的一個中心課題。關於冷高压活動的各階段过去已有些研究工作,其中有从熱力观點出發來討論冷高压的產生;有的从動力观點來討論高緯度冷高压的維持和爆發問題(寒潮爆發);也有从模型的实驗來討論冷高压的移動問題;也有人用高空氣流的匯流來解釋高压的加强或再生。
In this paper the outbreaks in the Far East of three types of polar highs in spring is analyzed by the"advective-dynamic"theory.The characteristics of the temperature-pressure field of the polar high at different stages,namely the stage of formation,and the west-eastward and north-southward movement,are presented respectively.The structure of the temperature-pressure field during cold outbreak is especially emphasized.Finally,two cases,one with a path of the polar(normal)axis type and the other with an extra-polar(abnormal)axis type are illustrated as examples.
