Abstract:
A real time testing result of precipitation forecast in 1998 flood period with a limited area nested grid model(LNGM) of η-coordinate was given.And it has indicated that this NWP with real-time initial field data of T106L19(the numerical weather forecast model of China)has a better TS forecast score of precipitation in the flood period in Hunan.In the second & third dekad of June and the third dekad of July in 1998 i.e.Hunan′s main flood period,the TS for precipitation forecast (24 hours) in the limited-area(hyetal region) with its center in Hunan,are 56.4%,33.9%,21.6% & 10.6% respectively to ≥1mm,≥10mm,≥25mm,≥50mm/24h,better than T106L19 and HLAFS(the mesoscale numerical weather forecast model of China),and the TS of precipitation ≥25mm/24h is 13.1% higher than HLAFS.
