摘要
20 0 2年 6月 2 4日夜间北京西南部地区的局地大暴雨是一次强地形雨 ,它是在对流层中低层有两层逆温以及边界层内中尺度低空急流与北京特定地形条件相互作用的情况下产生的。边界层内中尺度低空急流的发生、发展是低层偏东风与干、湿过程的“内边界效应”
The heavy rain occurred in the northwestern area of Beijing on the night of June 24,2002 is a severe orographic rainfall.The heavy rain under the conditions there were two inverse temperature layers in the middle and low troposphere is affected by the reciprocity between mLLJ and Beijing terrain.The generation and development of mLLJ in boundary layer is caused by deflective east wind in the low layer,the inner boundary effect in the dry and wet process,the latent heat release of strong rainfall and the reciprocity of them.
