The cloud model gives a complete structure of the partical microphysics of a convective cloud system over chinese mainland 云模式给出了中国陆地上两个对流系统的粒子微物理特征的完整结构。

The three - dimensional cloud model with hail - bin microphysics could simulate the characteristics of the severe storm such as life cycle , rainfall distribution and diameter of hail well , and also could produce strong downdraft and wind shear ( downburst ) 而利用三维强冰雹云模式对此次强风暴的生命史、降水分布、降雹的大小等要素做了较好的模拟，并能够模拟出伴随强风暴过程所产生的强下沉气流和及地面强风速切变(下击暴流) 。

The mechanism of the downburst formation was also investigated based on the cloud microphysics of the simulated storm and it was found that this downburst was primarily produced by hail loading , and enhanced by hail melting and rain evaporation . and the loading and the melting of hail played a very important role in producing the downburst . the gale at the surface was caused by the severe downburst 从云微物理学角度分析了此次局地性大风的形成原因，认为由高空冰雹粒子的拖曳产生的负浮力作用是促发强下沉气流产生的主要原因，其次是冰雹的融化和雨水蒸发冷却对下沉气流起加速作用，冰雹的拖曳和融化作用对下沉气流具有决定性的作用。

Rainfall is started mainly in cold portions . microphysics for ground rainfall consists of low - level warm portions in which precipitating particles are produced , growing through collision with cloud water and when descending into the warm portions below , ice - phase particles melt and continue to grow by collecting cloud water there . 4 ) 降水主要以冷雨过程发动，地面降水形成的微物理过程分别为低层暖云过程产生并通过碰并云水增长、降落到暖区的冰相粒子融化和融化的冰相粒子在云的暖区收集云水继续长大等三部分组成。

A severe convective storm accompanied with severe wind , heavy rain and hail on 23 august 2001 in beijing was simulated by mm5 initiated with ncep reanalysis data and a three - dimensional cloud model with hail - bin microphysics , which was initiated with the air soundings at beijing at 20 : 00 on 23 august 2001 , and some comparisons were also made between the simulated and natural storm 首先利用中尺度非静力平衡模式( mm5 ) ，模拟了2001年8月23日北京一次伴有大风、暴雨、冰雹的强对流天气发生发展的中尺度背景场，并根据mm5的输出结果分析了此次大风发生发展过程。
