摘要
利用斜压准地转滤波方法，通过引入一个反映ＣＩＳＫ机制的无量纲凝结潜热参数η（Ｚ），建立了描述热带大气的ＣＩＳＫ－Ｒｏｓｓｂｙ波模式，并求得了该模式的解析解。理论研究表明，考虑ＣＩＳＫ机制的ＣＩＳＫ－Ｒｏｓｓｂｙ波与经典的Ｒｏｓｓｂｙ波有明显差别，它可较好地解释热带大气３０—５０ｄ振荡现象。
In terms of a baroclinic quasi-geostrophic wave-filtering technique and through introducing a dimensionless parameter, η(z). of condensation-released heat that indicates the CISK mechanism, a model is established for describing tropical atmosphere CISK-Rossby waves. At the same time. the model's analytical solution has also been obtained. Theoretical study shows that there is pronounced difference between CISK-involving Rossby waves and classic Rossby waves. and CISK-Rossby waves can better interpret some aspects of 30 -50 day oscillation in the tropical atmosphere.
