摘　　要：利用海口雷达定量估测降水的格点数据与海南岛自动站实际观测到的降水数据的比值构建了折算系数,发现其折算系数服从正态分布。以折算系数的多倍标准差质控空间为检验实况观测降水的可信程度,结果表明,雷达定量估测降水对自动站实际观测降水有良好的质控效果,尤其适用于热带地区局地强降水的质量检验。In this paper, the ratio of the precipitation data and the precipitation data observed by the Haikou radar quantitative estimation of precipitation and the ratio of the precipitation data from Hainan Island automatic station is constructed, and the conversion coefficient is found to obey the normal distribution. This paper to the conversion coefficient of multiple standards poor quality space for the credibility of the test observations of precipitation, the results show that radar quantitative estimate precipitation on actual observations of precipitation of automatic weather station has good control effect, and is especially suitable for the heavy rainfall in the tropics local quality inspection.
