A baroclinic semi-geostrophic model with evaporation-wind feedback mechanism(EWFM) and CISK is established,two non-dimensional parameters a and η are introduced to represent EWFM and CISK,respectively.Analytic solutions of the model system are obtained,dynamics analyses and the model atmosphere calculations further confirm that EWFM and CISK are very important physical processes in leading to the low-frequency oscillations in the tropics.  相似文献

建立一个包含ＣＩＳＫ机制和蒸发－风反馈机制（Ｅｖａｐｏｒａｔｉｏｎ－ＷｉｎｄＦｅｅｄｂａｃｋＭｅｃｈａｎｉｓｍ，简写为：ＥＷＦＭ）的热带大气运动的无耗散、线性斜压半地转模式，引入反映ＣＩＳＫ的无量纲凝结潜热参数η和反映ＥＷＦＭ的无量纲参数α，并求得模式系统的解析解。动力学分析和模式大气的计算结果进一步说明了ＣＩＳＫ和ＥＷＦＭ的共同作用是激发和驱动热带大气低频振荡的重要物理过程。  相似文献
