摘要
利用含非绝热加热强迫的正压涡度方程。将非绝热加热作适当的参数化处理，对初始对称结构的热带气旋作了一系列数值试验，结果表明：不仅β项、平流项在热带气旋非对称结构的形成中有重要作用，而且非绝热加热对热带气旋的非对称结构亦有重要影响，从而验证了非绝热加热是热带气旋非对称结构形成的一种可能机制的结论。
ased on the initial symmetric tropical cyclone and parameterised diabatic heating a set of numerical experiment is made by using the barotropic,vorticity equation with diabatic heating forcing. It is found that the β term and nonlinear advection term has significant impacts on the tropical cyclone asymmetric structure, and the tropical cyclone asymmetric structure is influenced by the diabatic heating.It has been shown that the diabatic heating is a potential physical principle of the genesis of tropical cyclone asymmetric structure.
