摘    要:

概要回顾和总结了中国暴雨的卫星光谱遥感、被动微波遥感及主动微波探测的国内研究成果,并对卫星主被动仪器遥感研究中国暴雨的趋势进行展望。在卫星光谱遥感研究暴雨方面,学者们充分利用了红外通道亮温,监测暴雨云团发展变化,并结合再分析资料、雨量计观测结果、天气模式等,进行了很多具有应用价值的研究。在被动微波研究暴雨方面,主要将被动微波亮温结合变分同化系统,开展改善天气模式预报能力的研究,而很少利用被动微波多通道亮温来反演暴雨云参数。在卫星测雨雷达探测研究暴雨云结构方面,主要开展了暴雨降水结构的个例分析研究、暴雨强度及频次时空分布的统计分析研究。卫星多仪器与地基多仪器、模式资料、地面站和探空站等数据的综合应用,在未来暴雨监测及暴雨机理研究等方面将发挥重要作用;卫星多仪器遥感信号结合辐射传输模式和高分辨率云模式,可望未来获得暴雨云团内的大气动力学参数、大气热力学参数和云参数。

Abstract:
In this paper, the domestic research results of heavy rain in China by using instruments of spectral remote sensing, passive microwave remote sensing and active microwave radar on-board satellite are reviewed. In the study of heavy rain by satellite spectral remote sensing, the brightness temperature at infrared channels is applied to monitor the development of heavy rain cloud clusters, and conducted a lot of research with application value in combination with reanalysis data, rain gauge observation results and weather models. In the aspect of passive microwave research on heavy rain, studies on improving weather model prediction ability is mainly carried out by combining passive microwave brightness temperature with variational assimilation system, but rarely using passive microwave multi-channel brightness temperature to retrieve cloud parameters of heavy rain. Meanwhile, in the area of heavy rain structure measured by satellite precipitation radars, many heavy rain cases are analyzed, and the spatial and temporal distribution of heavy rain intensity and frequency in China are investigated. It is also pointed out that the combination of the satellite multi-instrument remote sensing signals with the radiation transfer model and the high resolution cloud model is expected to obtain the atmospheric dynamic parameters, atmospheric thermodynamic parameters and cloud parameters of the storm clouds in the future.
Keywords:heavy rain  satellite  infrared  passive microwave  space-based radar
