摘　　要：为了提高宁夏空中云水资源开发利用效率,利用2017-2019年FY2G卫星反演产品、自动站降水资料及微波辐射计反演产品,分析宁夏不同地区云微观特性的时空变化特征,研究液水含量的降水效率及云水资源开发潜力。结果表明:(1)剔除不合理数据后,FY2G卫星反演结果与微波辐射计反演结果相关性较好,反演产品基本上能够代表宁夏云水资源特征;(2)宁夏云中过冷层厚度大约在1.65~2km,液态水含量在0.02~0.5mm,云光学厚度的均值在3~7,云粒子有效半径在3~8μm;(3)宁夏云液态水降水效率为53.9%,人工增雨的潜力为46.1%,云液态水降水效率在夏季、秋季、春季、冬季依次降低。In order to improve the development and utilization efficiency of air cloud water resources in Ningxia, the temporal and spatial variation characteristics of cloud micro characteristics in different regions of Ningxia were analyzed by using FY2G satellite inversion products, automatic station precipitation data and microwave radiometer inversion products from 2017 to 2019. The precipitation efficiency of liquid water content and the development potential of cloud water resources were also studied. The results show that(1)after removing the unreasonable data, the FY2G satellite inversion results have a good correlation with the microwave radiometer inversion results, and the inversion products can basically represent the characteristics of cloud water resources in Ningxia.(2)The thickness of the cloud supercooling layer in Ningxia is about 1.65 ~2km, the liquid water content is 0.02~0.5mm, the average cloud optical thickness is 3~7, and the effective radius of cloud particles is3~8μm.(3) The precipitation efficiency of cloud liquid water in Ningxia is 53.9%, and the potential of artificial precipitation is 46.1%. The precipitation efficiency of cloud liquid water decreases successively in summer,autumn, spring and winter.
