中文摘要: 应用常规探空资料,对皖西南地区强风暴天气的s-r螺旋度进行了计算分析。结果表明。s-r螺旋度作为一个新的诊断量,对皖西南非孤立龙卷、大范围冰雹及距测站50km内的局地龙卷有较好的预报能力。
中文关键词: 强风暴，s-r螺旋度，风暴速度
Abstract:The helicity of severe storm processes had been counted and analysed with routine weather reports. The results show that helicity as a new diagnosis measure is helpful for forecasting of severe storm weather such as wide range of hailstone,no-isolated tornado and local tornado within 50km.
