利用一个两层半的热带海洋模式，采用数值实验的方法研究了热带海洋对于初始海洋混合层深度异常和大气季节内时间尺度热力强迫激发产生的Ｒｏｓｓｂｙ波和Ｋｅｌｖｉｎ波。研究表明，初始海洋混合层深度异常和大气热力强迫，可以在两层半热带海洋模式中激发产生东向传播具有Ｋｅｌｖｉｎ波性质的波动和具有Ｒｏｓｓｂｙ波性质的波动。热力强迫激发产生海洋Ｒｏｓｓｂｙ波和Ｋｅｌｖｉｎ波所需时间长于初始海洋混合层深度异常和大气季节内动力强迫激发产生两波所需时间，与大气季节内动力强迫激发的Ｒｏｓｓｂｙ波相比，初始深度异常与大气热力强迫激发产生Ｒｏｓｓｂｙ波具有不同的热力性质。
A two-and-a-half-half tropical ocean model was used to study the Rossby wave and Kelvin wave generated by tropical forcing in the initial ocean mixed layer anomaly and the thermal forcing in the atmospheric time scale. The results show that the initial ocean mixed layer depth anomaly and atmospheric thermal forcing can stimulate the fluctuations of the Kelvin wave and the Rossby wave in the two layers of semi-tropical oceanic model. The time required for thermodynamic forcing to generate marine Rossby and Kelvin waves is longer than the initial ocean mixed layer depth anomaly and the time required for dynamic forced excitation in the atmospheric season to produce two waves. Compared with Rossby waves excited by dynamic forcing in the atmosphere season, the initial depth anomaly It has different thermodynamic properties to the Rossby waves generated by thermal forced forcing in the atmosphere.
