中国气象局暴雨研究所支持的中尺度暴雨观测系统是中国长江中游地区中尺度对流系统的主要观测系统之一。IHR MHROS由移动C-POL和X-POL降水雷达、毫米波长云雷达、固定S波段降水雷达、全球定位系统网络、微波辐射计、无线电测深、风廓线雷达和散射计组成。这些仪器观测或反演的大气变量包括大气温度、湿度、风速和风向的廓线、MCS云和降水的垂直结构、大气水汽和云中的液态水。自2007年以来，这些质量控制的观测和反演已用于中尺度数值天气预报，以提高天气预报和MCS研究的准确性。这些长期观测为研究人员研究MCSs的形成-耗散过程以及为模型师改进MCSs的模拟提供了最全面的数据集。作为系列文章的第一篇，我们简要介绍了IHR MHROS，并描述了它的主要仪器的规格。然后，我们综合分析了2014年7月3-5日一次暴雨个例的IHR MHROS观测资料以及IHR MHROS资料在改进模式模拟中的应用。在一系列论文中，我们将利用IHR MHROS观测资料，试探性地回答有关长江中游地区MCS和梅雨锋系统的几个关键科学问题。
The Mesoscale Heavy Rainfall Observing System (MHROS), supported by the Institute of Heavy Rain (IHR), Chinese Meteorology Administration, is one of the major systems to observe mesoscale convective systems (MCSs) over the middle region of the Yangtze River in China. The IHR MHROS consists of mobile C‐POL and X‐POL precipitation radars, millimeter wavelength cloud radar, fixed S‐band precipitation radars, GPS network, microwave radiometers, radio soundings, wind profiler radars, and disdrometers. The atmospheric variables observed or retrieved by these instruments include the profiles of atmospheric temperature, moisture, wind speed and direction, vertical structures of MCS clouds and precipitation, atmospheric water vapor, and cloud liquid water. These quality‐controlled observations and retrievals have been used in mesoscale numerical weather prediction to improve the accuracy of weather forecasting and MCS research since 2007. These long‐term observations have provided the most comprehensive data sets for researchers to investigate the formation‐dissipation processes of MCSs and for modelers to improve their simulations of MCSs. As the first paper of a series, we briefly introduce the IHR MHROS and describe the specifications of its major instruments. Then, we provide an integrative analysis of the IHR MHROS observations for a heavy rain case on 3–5 July 2014 as well as the application of IHR MHROS observations in improving the model simulations. In a series of papers, we will tentatively answer several key scientific questions related to the MCS and Meiyu frontal systems over the middle region of the Yangtze River using the IHR MHROS observations.
