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。
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.
