一次东北冷涡降雹过程的防雹效果分析
Analysis of Hail Suppression during a Northeast Cold Vortex
摘要
Abstract
This study analyzes the effectiveness of a hail suppression operation using anti-aircraft artillery during a northeast cold vortex event in Changchun on July 6,2023,based on ERA5 reanalysis data,weather radar data,and minute-resolution precipitation observations from automatic stations.The results showed that before the operation,strong radar echoes(≥45 dBZ)rapidly intensified within a short period,covering up to 70.4%of the area.The Vertical Integrated Liquid(VIL)exhibited a notable surge,with a maximum increase of 41 kg/m2 within 12 minutes.The Hail Index(HI)also indicated a high probability of hail.Following the operation,the maximum echo intensity gradually decreased,the area coverage of echoes≥45 dBZ declined,echo volumes dispersed and split,the central height of echoes noticeably lowered,VIL decreased,and HI gradually dropped to zero.Compared to the upstream and downstream control areas,the operational area exhibited lower total precipitation,reduced variability in precipitation intensity,and fewer distinct precipitation peaks.The maximum precipitation peak in the operational area occurred after the operational effects had diminished.These findings suggest that the hail suppression operation effectively inhibited the natural development of hail.关键词
