本文采用了包含热力强迫和涡动耗散的三维非线性动力学模式，从系统稳定性的角度出发，探讨了夏季东亚副热带地区的环流状况，东亚大陆季风雨带和南海季风槽雨带的凝结加热以及扰动流的相互作用等因素对西太平洋副热带高压进退的制约和影响。给出了反映系统稳定性状况的能量判据，井据此进行了动力学分析和模式大气的计算。研究结果为一些天气分析事实提供了动力学解释，得到了一些新的见解，并为判断和预测西太平洋副热带高压在东亚上空的活动提供了参考依据。
In this paper, a three-dimensional nonlinear dynamic model including thermal forcing and vortex dissipation is adopted. From the perspective of system stability, the circulation conditions in the East Asia subtropical region in summer and the condensation of the East Asian continental monsoon rain belt and the South China Sea monsoon trough are discussed Heating and disturbance flow interactions and other factors on the West Pacific subtropical high pressure advance and retreat constraints and impact. The energy criterion that reflects the stability of the system is given and the dynamic analysis and the calculation of the model atmosphere are performed accordingly. The results provide some dynamic explanations for some of the weather analysis facts and give some new insights and provide references for judging and predicting the activities of the western Pacific subtropical high over East Asia.
