Availability analysis of global forecast system forecasting rainfall considering forecast horizon weights

Lu D

Abstract

Based on the statistical analysis of global forecast system(GFS)forecasting rainfall and actual rainfall in Huanren basin,considering different forecast horizon weights,the availability of GFS rainfall forecast in a period of 1-3days is analyzed.The computing results show that the availability of GFS rainfall forecast considering forecast horizon weights is obviously higher than that without considering forecast horizon weights.The proposed method has a great significance for reservoir operation.
