本文从无粘、非绝热的Boussinesq方程出发,凝结加热参数化采用Emanuel的WaVe-CISK方案,研究了在考虑凝结加热时β中尺度非线性不稳定问题,发现潜热释放会加强不稳定,且其作用时段在不稳定发展的中后期;非线性作用使得波形发生变化,也改变了波动的传播速度。
Considered the condensation heating of Wave-CISK scheme, this paper gave a study of meso-β instability with the inviscid, diabatic Boussinesq equations. It shows that the condensation heating could feed back the system of meso-β and it mainly occurred in metaphase and anaphase. Nonlinear factor would change the wave form and its spread velocity.
