摘要:
利用Micaps、Necp、多普勒雷达等资料分析2016年4月发生在上思县的冰雹天气过程,结果表明:冰雹过程发生在200hPa高空急流、500hPa高空槽、中低层暖湿急流、切变线共同配合的环流背景下;0℃层和-20℃层均有利于冰雹的发生发展,且强回波核心高度伸展到-20℃层以上;多普勒雷达上具有大于65dBz以上的强回波,并伴有旁瓣以及三体散射长钉,低层弱回波区等特征,并且强回波区与速度场上的中气旋、低层径向辐合相关。
Abstract:
Using the data of Micaps、Necp and Nanning Dopple radar, a hail weather process on April10, 2016 in Shangsi, was analyzed with the Causes, The results are as follows:The process takes place under circulation background at 200 h Pa hail jet stream, 500 h Pa trough, warm and humid in the lower jet stream, together with the shear line; There were favorite height conditions of 0℃ and -20℃ layer for the hail, and the height of severe echo reached above the layer of -20℃; There are many features of Dopplar Radar echoes,such as a strong echo greater than 65 d Bz above,Sidelobe, three-body scatter spike(TBSS),weak echo region(WER), and the strong echo areas are related to the areas of Mesocyclone,wind convergence in Dopplar radar velocity field.
