| Abstract: | An improved GB quantitative precipitation forecasting model is proposed.By introducing latest research result in related cloud physics a new type of hydrometeors size distribution that is in good accord with observed data,a new ground rainfall forecasting formula is derived.The developed propagation and updata equations in realtime are exact state estimator for liner,scalar systems when observables are time integrals in an interval of linear function of the state.The model is tested with storm data of three meteorological stations in Hubei Province and the results are satisfactory. |
