摘 要: | 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 representEWFM and CISK,respectively.Analytic solutions of the model system are obtained,dynamicsanalyses and the model atmosphere calculations further confirm that EWFM and CISK are veryimportant physical processes in leading to the low-frequency oscillations in the tropics.
