摘要
针对小尺度深凹地形的特点 ,建立了一个高分辨的、非静力的二维边界层模式 ,采用能量 ( E- ε)闭合方案 ,考虑了太阳短波辐射及其在地表面的不均匀分布 ,地 -气系统的长波辐射、潜热和感热输送 ,以及地表面与土壤层的热传导等物理过程 .利用该模式 。
A high resolution, nonhydrostatic,two dimensional,microscale ABL prognostic model was established in this paper considering hte characteristics of deep concave terrain.The simple (E ) cllsure scheme was used in the model. The radiation of the sun and its uneven distribution on the ground,the long wave radiation of the earthatmosphere system,the sensible heat and latet heat and the heat flowing into the microscale circulation over the real terrain of a certain deep concave open pit mine was studied using this model.
