摘　　要：本文主要研究了存在凝结加热时的对称不稳定,对流凝结加热采用了Wave-CISK方案.计算结果表明对流凝结加热通过CISK机制可以产生传播的对称不稳定扰动,且对扰动的传播方向、增长率及结构有影响.In this paper the symmetric instability is studied when the condensation heating existing. The wave-CISK parameterized scheme is used in the convection condensation heating term. The calculation results show that the disturbance, of propagating symmetric instability is produced through CISK mechanism and the propagating direction, the growing rate and the structure of disturbance are affected by convection condensation heating.
