石羊河流域面雨量预报方法研究
Study on forecast method of surface rainfall in Shiyang River Basin
摘要
Abstract
Using European Centre for Medium Range Weather Forecasts numerical forecast grid materials and precipitation materials in six weather stations from 1996 to 2008 and precipitation materials of 47 encryption automatic region stations from 2007 to 2008 in Shiyang River basin, forecast factors were initially elected with Press criterion and forecast factors were precisely selected with stepwise regression method, 1 to 7 day precipitation prognostic equations of cold and warm season were built with optimal subset regression. County precipitation forecasts were interpolated to region stations as foundation of various counties precipitation objective forecasting product using linear interpolation method, 1 to 7 day surface rainfall forecast pattern was manufactured with arithmetic average method in Shiyang River Basin. The surface rainfall forecast pattern was invested to service movement, of which forecast ability was stronger and good forecast service progress was made. Objective and effective instruction product was provided for the basin surface rainfall prediction.关键词
