利用滨州地区1988～1997年的雷达回波、降雹资料及有关的高空探测资料，对冰雹云的雷达回波参数和环境场要素进行了统计分析。结果表明：降雹与雷达回波顶温度、回波强度、0～20℃之间云体的厚度、700hPa上的比湿及云体的冷暖厚度之比等参数有关。在此基础上，建立了冰雹的短时预报方程，并为人工防雹提供可作为依据的简明判据。 Based on the radar echoes and hail data from 1988 to 1997 in Binzhou area and the related high-altitude exploration data, the radar echo parameters and environmental field elements of the hail cloud are statistically analyzed. The results show that the hail is related to the parameters of radar echo top temperature, echo intensity, the thickness of the cloud body between 0 ~ 20 ℃, the specific humidity at 700hPa and the ratio of the body temperature to the body temperature. On this basis, a short-term forecasting equation of hail is established and concise criteria for artificial hail prevention can be provided.
