The cloud model gives a complete structure of the partical microphysics of a convective cloud system over chinese mainland 云模式給出了中國陸地上兩個對流系統(tǒng)的粒子微物理特征的完整結(jié)構(gòu)。
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 ) 而利用三維強(qiáng)冰雹云模式對此次強(qiáng)風(fēng)暴的生命史、降水分布、降雹的大小等要素做了較好的模擬,并能夠模擬出伴隨強(qiáng)風(fēng)暴過程所產(chǎn)生的強(qiáng)下沉氣流和及地面強(qiáng)風(fēng)速切變(下?lián)舯┝? 。
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 從云微物理學(xué)角度分析了此次局地性大風(fēng)的形成原因,認(rèn)為由高空冰雹粒子的拖曳產(chǎn)生的負(fù)浮力作用是促發(fā)強(qiáng)下沉氣流產(chǎn)生的主要原因,其次是冰雹的融化和雨水蒸發(fā)冷卻對下沉氣流起加速作用,冰雹的拖曳和融化作用對下沉氣流具有決定性的作用。
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 ) 降水主要以冷雨過程發(fā)動,地面降水形成的微物理過程分別為低層暖云過程產(chǎn)生并通過碰并云水增長、降落到暖區(qū)的冰相粒子融化和融化的冰相粒子在云的暖區(qū)收集云水繼續(xù)長大等三部分組成。
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 首先利用中尺度非靜力平衡模式( mm5 ) ,模擬了2001年8月23日北京一次伴有大風(fēng)、暴雨、冰雹的強(qiáng)對流天氣發(fā)生發(fā)展的中尺度背景場,并根據(jù)mm5的輸出結(jié)果分析了此次大風(fēng)發(fā)生發(fā)展過程。
