A Study of Optimizing Initial Parameter of One-Dimentional Cumulus Model

Fujian precipitation enhancement commanding system refers to a one-dimentional time dependent cumulus model of Hu ZhiJin.A research method of determining initial field of cumulus model in weather modification is discussed.Considering different weather type affecting model initial parameter,the method of determining sensitive parameter priority to other correlative parameter is developed synthetically.By classifying,it is proved that the model initial field is good correlative with weather type.It is obtaind that the precipitation forecast accuracy of model is greater than 75% and that is available to forecast cumulus height.It is also obtained that sensitive parameter (initial disturbance temperature) and mean surface maximum temperature are carrelative each other.
