| 摘 要： | 毫米波测云雷达作为一种新型的气象探测装备,在云粒子的探测上具有一定的优势。基于毫米波测云雷达的探测数据和探空仪获取的温度数据,设计云粒子相态识别算法。采用该算法,对2017年1月19日、2月7日、3月20日的毫米波测云雷达探测数据进行了云粒子相态识别和过冷水等数据产品反演。分析结果表明,逆温层与过冷水层高度正相关,过冷水和冰晶交汇区附近会出现湿冰相和混合相,过冷水含量与融化层亮带呈一定的负相关关系,整体相态识别结果与实际相吻合,验证了粒子相态识别算法的有效性。

| Abstract: | The cloud particle phase recognition algorithm is designed according the principle and mechanism to recognize cloud particle phase,which are adopting microwave remote sensing,this work has been done on the basis of understanding the technical performance and detection superiority of millimeter wave cloud radar.The distribution characteristics of the supercooled water in the cloud are summarized by analyzing the data of cloud particle phase of typical weather,which data are including the the Ka-band ground-based millimeter wave radar and the sounding in the actual observation experiment.The identification results are in good agreement with the cloud micro-physical process principle and observed weather condition. |
