| 摘 要： | 利用MM5数值模式对山东半岛北部2005年12月3～4日暴雪天气进行模拟试验,研究了山脉地形和渤海对半岛北部冷流暴雪的影响,实验表明半岛北部的山脉地形对冷流暴雪的落区和强度影响较大,有山脉地形时降雪强度增大,降雪中心略北移,无渤海时没有明显降雪;同时,保留地形时的上升运动、低层风场辐合和正涡度区都要比无地形和渤海时大得多.

| Abstract: | By use of the MM5 numerical model,we simulate and analyze the effect of terrain and Bohai Sea on the cold-air sonwstorm in northern ShanDong Peninsula on Dec.03-04, 2005. The results show that terrain and Bohai Sea play a very important role in the cold-air snowstorm.The precipitation increases obviously in the upwind direction of mountain,there is no snow falling obviously without Bohai Sea. Also, terrain makes stronger lower layer convergence and positive vorticity area. |
