中文摘要: 根据山东省雷达回波资料、天气和灾情实况，统计了回波顶高Hm、强回波区顶高Hz、回波强度Z与降雹概率的关系；给出单、双参数判别雹云的指标；提出用3参数降雹条件概率法判别雹云；指出了3参数识别指标对降雹的预示作用，这对强对流天气的短期预报具有一定的实用价值。
中文关键词: 回波参数，雹云识别，降雹概率，降雹时间
Abstract:Based on the radar echoes,information of weather conditions and the catastrophe in Shandong prvince,the correlation between the top height of echo vault Hm,severe echo vault region Hz,the strength of the echo vault Z and the hail fall probability was analysed. The discrimination indices of the hail in single and bi parameter were provided. The parameters formula incorporating with conditional probability of hail was used to identify hail cloud. It showed the use of the three parameters discriminatory index for hail forecast. This is very important for the forecasting of severe convective weather.
