Description
Summary:This study evaluates the performance of the regional operational model at Central Weather Bureau (CWB), the Non-hydrostatic Forecast System (NFS), in capturing the general distribution and eastward propagation of warm-season rainfall within the diurnal cycle in Hovmoler (longitude-time) space over the East Asian continent. The Tropical Rainfall Measuring Mission (TRMM) 0.25?rain-rates are used to evaluate the NFS coarse domain (45 km) 12 - 36 h QPFs during May - August, 2002 - 2005 both qualitatively and quantitatively.
