摘要:
利用雷达三维组网产品、雷达风场反演产品、冰雹识别组网产品、龙卷涡旋特征识别移动路径产品，对2021年华东、华中、东北等地发生的4次强对流天气进行了应用分析。结果表明，雷达三维组网产品完整地记录了涉及范围较广的4·30雷暴大风从初生到消亡整个发展演变过程，该产品叠加地面单站大风、雷电活动情况更能直观地反映出雷暴、大风出现的范围和强度；冰雹识别组网产品识别出的冰雹尺寸等参数与实况出现的情况基本相符；雷达风场反演产品能很好地揭示龙卷的旋转程度；经过质控后的龙卷涡旋特征产品一定程度上能够反映龙卷移动路径；双偏振相关系数CC产品又为龙卷是否着地提供了很好的判断依据。
Abstract:
Using radar three-dimensional networking products, radar wind field inversion products, hail identification networking products, and tornado vortex feature identification moving path products, the application analysis of four severe convective weather in East China in 2021 was carried out. The results show that the radar 3D networking product completely records the whole development and evolution process of the thunderstorm gale on April 30 from birth to extinction. The product can more visually reflect the scope and intensity of thunderstorms and gales by superimposing the gales and lightning activities of a single ground station. The hail size and other parameters identified by the hail identification networking product are basically consistent with the actual situation. Radar wind field inversion products can well reveal the rotation degree of tornado. The tornado vortex characteristic products after quality control can reflect the tornado movement path to a certain extent. The dual polarization correlation coefficient CC product also provides a good basis for judging whether the tornado is on the ground.
