摘要
利用探空资料对垂直累积液态含水量(VIL)进行了分层,并分别计算出0℃层上、下两层的VIL值以及这两层的比值。再利用VIL、分层VIL以及VIL比值分析了2006年7月24日发生在山西阳泉的一次冰雹过程,发现在冰雹发生前后VIL、分层VIL以及VIL比值有明显的规律可循,这对冰雹天气的短时临近预报以及对冰暴灾害的防御有重要指导意义。
The Vertically integrated liquid（VIL） can be stratified using the radiosonde data.And the VIL at the upper and lower 0℃ layers and ratio of the two layers were calculated too.Moreover,VIL,stratified VIL and ratio of VIL of a severe hail stooting process that took place in Yangquan,Shanxi Province on July 24,2006 were analyzed.It is found that there are some obvious regular rules about VIL,stratified VIL and ratio of VIL before and after the hail occurrance.Those have significant guiding in short-term weather forecasting and disaster prevention of storm.
