摘要:
根据湖南怀化历史雷达资料,统计分析了垂直液态含水量、最大反射率等降水特征因子以及云内凝结液态水,并结合全省区域观测站同步雨量资料,采用"按行政区域划分到县"方法,计算出怀化地区实时地面降水量与降水效率。分析结果表明:选取的2015年怀化地区层积混合云降水个例具有一定的代表性,怀化地区上空垂直液态含水量充沛,最大反射率为57dBz,最大垂直液态含水量为2.40*107m3,6min平均垂直液态含水量为2.16*107m3
Abstract:
According to the statistical analysis of the vertical liquid water content, maximum reflectance and other precipitation feature factors by using Huaihua history radar data and the rainfall data, the real time land surface precipitation and precipitation efficiency in Huaihua were calculated accurately by using the method of ‘dividing the county according to the administrative area’. The results show that:the selected stratus and cumulus mixed clouds are representative; the Huaihua area has high vertical liquid water content with the 57dBz maximum reflectivity, is 2.40*107m3the maximum vertical liquid water content, 2.16*107m3the 6min average vertical liquid content, 4.81*106m3the 6min average rainfall and 18.21% precipitation efficiency.
