摘要: 本文给出-个非静力全弹性大气的含地形的中-β模式,利用该模式的二维版本模拟研究了地形云。所给出的结果,不仅描述了地形云的发展,而且呈现了多种气流过山现象,如焚风、下坡风,以及水力学中的"水跃"等。说明模式有较好的功能。

Abstract: This paper describes a nonhydrostatic and full-elastic meso-β scale model including the effects of topography. By use of the two-dimensional version of this model the topographic clouds have been simulated. The results of simulation indicate that: not only the formation and evolution of topographic cloud but also various phenomena of airflow over mountain, such as foehn wind, dowuslope wind and "hydraulic jump" named in hydraulics, have been well reappeared.
