联合雷达网和卫星定量监测与预报长江流域大范围降水

COMBINING RADAR NETWORK WITH SATELLITE FOR QUANTITA TIVELY OBSERVING AND FORECASTING LARGE AREA RAINFALL OVER THE YANGTZE RIVER VALLEY

在吸取欧洲国际雷达网以及英国ＮＩＭＲＯＤ系统先进经验的基础上，根据我国实情，以长江中游数字化雷达网和ＧＭＳ卫星为主要技术手段，并结合数值风场预报，研制成大范围降水实时定量监测和预报的自动化系统ＬＡＲＯＲＡＳ．研究成功定量测估长江流域大范围降水累积量的实时处理技术，其产品对防汛抗洪和大型水库工程建设具有重大应用价值．

Based on the experiences of the European International Radar Network and the British NIMROD system and according to actual condition in China, a large area rainfall observation in realtime automatic system (called LARORAS) has been developed by using digitized radar network in middle reaches of Yangtze River and GMS satellite as the main technical methods and incorporating numerical wind field prediction, in which the processing technique in real time for quantitatively measuring and estimating large area rainfall accumulation over the Yangtze River valley has been successfully developed, its products have great values for preventing flood and construction of large reservoir engineering. 
