摘要
对新一代天气雷达(CINRAD/SA)探测到的4次三体散射现象的冰雹天气过程进行分析,通过分析得出以下结论:三体散射现象首先在高层出现,强中心回波强度达60 dBz以上,三体散射是降大雹的指示性指标并有一定的提前量,同时可能伴有灾害性大风。
An analysis is made of four hail events in which the ＂three-body scattering＂ phenomenon was detected by means of the new-generation weather radar （CINRAD/SA） at Longyan of Fujian Province. The results show that the three-body scatter phenomenon appears generally at upper levels at first; the strong echo center is greater than 60 dBz; the three-body scatter feature is a good indicator of severe hails with a certain time lead, and meanwhile can be used in strong wind forecasting.
