| 摘 要： | 根据近年来大别山地区高密度雨量站资料,利用GIS技术形成的更为精细的栅格点坡度和高度数据,得出雨量与山区坡度和高度的具体关系,并由此推算出两个子流域发生山洪灾害的雨量阈值;实时通过数据服务器获取前期逐时雨量资料,形成24 h和6 h雨量,根据雨量关系式求算面雨量,与山洪灾害雨量阈值进行比较,给出是否发生山洪灾害的预警信息;及时发布预警信息,将山洪灾害的预警信息在淮河流域气象中心进行实际应用。

| Abstract: | According to high density precipitation data of Dabie Mountain in recent years,the specific relationship of rainfall with mountainous slope and height is established by using GIS technique to form more careful grid slope and height.And rainfall threshold of flash flood disaster in two sub-watersheds is calculated.Real-time hourly rainfall data are accessed through the data server,forming 24 hours and six hours rainfall.Warning information of flash flood disaster is given according to rainfall formula calculating area precipitation and comparison with flash flood disaster area rainfall threshold.Warning information is released at real-time,and it is practically applied to Meteorological Center of Huaihe River Basin. |
