中文摘要: 通过对永登防雹试验基地1971~1978年6~8月09时634次无线电探空资料与地面实况、天气现象进行分类研究,发现露点零度的高度具有指示雹日的意义;300~600hPa层间的Σ(T─Td)和300~500hPa间的Σ(T─Td)。具有指示降雹强弱的意义,为冰雹预报提供依据,具有实用意义。

Abstract:Based on the 634 times of sounding data at 9 o'clock in June,July and August from 1971to 1978 at the hail suppression site in Yongdeng,Gansu province,the classification of weather phenomena and the surface observation were analysed. The results show that the height of 0'C dew-point temperture is an indicaton of halfday and the dew-point depressions at upper levels are of the signification representing the hail intensity. These indicators provide a reference for hail forecast.
