| 本文采用非地转非静力条件下存在对流凝结加热反馈的Boussinesq方程组,借用Emanuel(1982)的Wave-CISK方案来考虑凝结反馈作用,并应用Green函数方法和Fourier方法,求得了任意加热廓线时对称不稳定的流函数的解析表达式及其频散关系。本文还对取某些特定的加热廓线时的情况进行了讨论。 |

| Abstract: |
| In this paper the symmetric instability is investigated analytically by use of Green's function method and Fourier analysis, Ageostrophic and nonhydrostatic Boussinesq equations with the feedback of condensation heating, which is calculated by the wave-CISK parameterized model (Emanuel 1982),are used in the investigation. The analytic expressions of stream functions for any heating profiles with symmetric instability are obtained and so is their relation of dispersion. A number of specified heating profiles are assumed and discussed. |
