The Water Cycle Research (WCR) project will develop a continuous thunderstorm monitoring system over the African continent for characterization of convective precipitation variability at spatial resolutions needed for hydroclimate studies and applications. In the absence of ground weather radar and reliable surface measurements of precipitation over vast regions of Africa, space observations provide a valuable, unique means of monitoring rainfall variability. Dr. Anagnostou (U Conn) and co-PI Dr. Williams (MIT) will extend the lightning based monitoring system that is operative over Europe, West Asia, and the Atlantic Ocean to the African continent, from deployment of sferics-based radio receivers at four African sites. Cloud-to-ground lightning events will be retrieved in real time, and combined with satellite infrared and microwave observations to monitor convective precipitation and thunderstorm rain-rates. The fully implemented system will provide reliable, real-time data for hydro-meteorological forecasting and water resource management, with considerable socio-economic benefits to the African people.

水循环研究项目将在非洲大陆开发一个连续雷暴监测系统，以水文气候研究和应用所需的空间分辨率描述对流降水变化的特征。 在没有地面气象雷达和对非洲广大地区降水量进行可靠的地面测量的情况下，空间观测为监测降雨量的变化提供了一种宝贵而独特的手段。 Anagnostou博士（康涅狄格大学）和共同PI威廉姆斯博士（麻省理工学院）将扩大闪电为基础的监测系统，是在欧洲，西亚和大西洋到非洲大陆，从部署基于sferics的无线电接收器在四个非洲网站。 将以真实的时间检索云地闪电事件，并将其与卫星红外和微波观测相结合，以监测对流降水和雷暴雨率。 该系统得到充分实施后，将为水文气象预报和水资源管理提供可靠的实时数据，给非洲人民带来巨大的社会经济效益。
