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。
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.
