摘要
利用MICAPS资料和多普勒雷达资料对2003年7月22日和2006年4月23日发生在准噶尔盆地南缘两例强冰雹天气过程进行对比分析,结果表明:这两例强冰雹天气都具备了强而厚的不稳定大气层结、充沛的水汽和强的风垂直切变,但天气形势0℃和-20℃层的高度和厚度、高低空急流的强度以及雷达回波的强度和尺度等均存在明显差异。
Based on the data of MICAPS and Doppler radar observation, two cases about strong hail weather system evolution happened on 2003-22-7 and 2006-4-23 were analyzed by the method of contrastive analysis. The results showed： these strong hail weathers above all had strong and thick unstable atmosphere stratification, abundant vapor and strong vertical wind shear, on the other hand, the synoptic situation, the height and thickness in 0 ℃ layer and -20℃ layer, the intensity of jet stream both at upper and lower level, and the intensity and thickness of radar echo etc. existed obvious differences.
