| 摘 要： | 通过甘肃永登、岷县防雹试验基地1979~1987年获取的1 d 4次无线电探空资料,对照地面实况,对强冰雹、弱冰雹、雷雨、阵雨、阴天、晴天6类天气的高空风进行分析研究,发现强雹暴在降雹前期低空风向切变、中空风速切变、高空急流等与其它类型天气比较具有显著的差异,这对于预报雹暴天气和雹暴形成机制的研究具有指示意义。

| Abstract: | Based on aerological observations at the hail suppression experimental stations of Yongdeng and Minxian counties of Gansu Province during 1979-1987,as well as surface meteorological observations at the same time,the upper winds under the six different weather conditions of strong hailstorm,weak hailstorm,thunderstorm,shower,overcast and sunshine were analyzed.Results show that significant defference prezented in low air wind direction shear,middle air wind velocity shear and jet in upper air before haill falling under the strong hailstorm weather condition compared with those of other weather conditions,which is useful to forecast hailstorm and study its formation mechanism. |
