使用河南省气象台站1982~1997 年4~8 月地面报表和同时期雷达回波资料统计分析了40 次区域性冰雹过程(相邻3 站以上降雹)的天气特征、回波参数特征,找出了相关性较好的各种预报判据和多普勒天气雷达强度场、速度场上的图像特征,为制作冰雹的短时预报、雷达监测及人工消雹工作提供科学的依据。
The weather characteristics and echo parameter characteristics of 40 regional hail processes (hailstones over 3 stations) were statistically analyzed using surface reports and simultaneous radar echo data of Henan Meteorological Station from April to August of 1982 ~ 1997. The correlation forecast is good and the Doppler weather radar intensity field, the velocity field of the image features for the production of hail short-term forecast, radar monitoring and artificial hail work to provide a scientific basis.
