摘要
在卫星云图分析的基础上，结合常规气象资料和Ｔ１０６数值产品分析了北京地区１９９８年７月２３日局地特大暴雨的成因和中尺度系统在ＩＲ云图中的特征。中尺度系统是在有利的天气尺度背景下。
On the basis of analysis of the satellite cloud picture,combined with routine meteorolog ical information and the product of T106 mathematical forecast,the mechanic of a local torrential rain in Beijing on 23 July,1998 and the character of mesoscale structure about IR cloud atlas were analyzed.It is shown that the advantageous conditions are favorable to the birth and development of the mesoscale system including the favorable synoptic condition,the water vapor convergence and high instability energy.
