摘要: 2007年8月18日夜里超强台风“圣帕”紧靠福建沿岸时,在其移动方向的右前侧约300km的温州市苍南县龙港镇的工农业造成了严重灾害。灾害发生后,当地干部群众迫切要知道是否因龙卷风成灾。为了查明成灾原因和发生机理,温州市气象局及时组织专家组奔赴现场开展灾情调查。通过利用灾害现场调查资料、多普勒雷达观测资料、群众目测、陈述等材料,综合比对龙卷风的特征,结果表明:此次灾害确实是一次台风外围环流中的强龙卷风所致。截至目前,虽然多谱勒雷达对龙卷风的监测能力有较大提高,但是龙卷风雷达反演的效果不理想,器测龙卷风仍存在较大困难。同时,数值模式对龙卷风等微小尺度系统的预测能力仍有待于提高和进一步发展。
