用动力分析和数值计算的方法讨论了大气对海温热力强迫的响应。结果表明:对于行星尺度系统,海温热力场的持续强迫作用可以很快激发出稳定的大气平衡态响应,该响应表现出明显的大尺度东-西及南-北向涛动特征。对于天气尺度系统,海温热力场则主要激发出大气低频振荡。研究结果揭示了海温热力构型与大气响应形式的基本对应关系和动力过程,提出了一些新观点。
用動力分析和數值計算的方法討論瞭大氣對海溫熱力彊迫的響應。結果錶明:對于行星呎度繫統,海溫熱力場的持續彊迫作用可以很快激髮齣穩定的大氣平衡態響應,該響應錶現齣明顯的大呎度東-西及南-北嚮濤動特徵。對于天氣呎度繫統,海溫熱力場則主要激髮齣大氣低頻振盪。研究結果揭示瞭海溫熱力構型與大氣響應形式的基本對應關繫和動力過程,提齣瞭一些新觀點。

Dynamic and numerical methods are used to discuss the atmospheric response imposed by SST thermal forcing.The results show that,for planetary scale systems, the standing SST thermal forcing can quickly excite a stable atmospheric equilibrium state response,which is characterized by obvious large-scale teleconnection oscillation in east-west and south-north directions. For synoptic scale systems, the SST thermal forcing mainly excites the atmospheric low-frequency oscillation .Some basic relation and dynamic process between SST thermal forcing and atmospheric response pattern are revealed and some new viewpoints are presented.
