Numerical Study for the Influences of Orographic Dynamic on Cloud and Precipitation in North China
地形动力作用对华北暴雨和云系影响的数值研究

Orographic dynamical effects on cloud and precipitation arediscussed through the numerical experimentsof a North China rainstorm case on 22~24 July 2005 by using Advanced Regional Prediction System(ARPS) model.The researched results show that the distribution and size of horizontal and vertical wind will obviously change due to terrain height variety.Increase of terrain height is favorable to the development of horizontal wind divergence and upward convection,especially the development of mid-high cloud.Owi...
