摘要
利用MM 5中尺度数值模式对 1998年 6月 8～ 9日华南暴雨进行了模拟 ,用Reisner霰方案模拟了可分辨尺度降水 ,详细分析了暴雨的微物理过程。结果表明 ,Reisner霰方案对华南暴雨具有较好的模拟能力。在降水最大时段 ,霰和云水是形成雨水的主要来源 。
The heavy rainfall during 8～9 June 1998 is simulated by using the non hydrostatic mesoscale MM5(V3). The discriminable scale rainfall is simulated by using the Reisner Graupel scheme. Results show that the Reisner Graupel scheme has a better ability to simulate the microphysical process . During the period of the maximal precipitation, the most important sources for the rainwater are the graupel and cloudwater. And the cloudwater′s accretion is the main microphysical process for the graupel.
