在定常条件下,利用简化的大气运动控制方程,分析了气旋与反气旋的基本特征。在此基础上,利用常微分方程的定性分析与求解,获得了气旋和反气旋轨道的解析解。接合气旋与反气旋的基本特征,论证了正负阻尼在气旋和反气旋运动中具体体现,并从物理机理上说明产生气旋和反气旋运动中正负阻尼的差异在于水平辐合在低层的不同。

英文摘要：

Under steady conditions, simplified control equations of atmospheric motion are used to analyze the basic characteristics of cyclones and anticyclones. On this basis, analytic solutions of cyclonic and anti-cyclonic trajectories are derived by qualitatively analyzing and solving ordinary differential equations. By combining the basic characteristics of cyclones and anticyclones, it is demonstrated that positive and negative damping behaviors are present in cyclonic and anti-cyclonic motions and that the physical mechanism of the negative damping in these motions results from various tvlaes of horizontal convergence at low levels.
