摘　　要：结合2015年6月6日冷涡前部飞机增雨降水过程,利用实测资料对国家人影模式产品进行定性检验,包括对云系和降水进行对比检验,结果表明:模式对于云系的发展演变趋势、移动方向预报与实测基本一致,但云系移动速度比实况稍慢,导致预报云带整体偏西;预报雨带的分布、降水量级与实况较为一致。Combined with precipitation process of the front of the cold vortex on June 6,2015,the qualitative test of the national silhouette model products was carried out using the measured data,including the comparison test of the cloud system and precipitation.The results show that,the predictions of the evolution trend and moving direction of the cloud system by the model are basically consistent with the observations,however,the moving speed of cloud system is slower than that of actual cloud system,which leads to the prediction that the whole cloud belt is westward;The distribution and precipitation level of the forecasted rainband are consistent with the actual situation.
