| 摘 要： | 应用逐时同化预报系统CHAF进行加密探空资料同化试验,比较了同化加密探空资料与仅同化常规探空资料所得同化分析场和模式预报结果的差异.同化加密探空资料所得分析场水汽的均方根误差减小,水汽条件和大气环流形势与实况更接近.以加密同化探空资料所得分析场为模式初始场进行预报,雨区的分布和降水量级都较控制试验有改善.分析模式预报改...

| Abstract: | Using the system of CHAF(Cycle of Hourly Assimilation and Forecast),the validity of assimilating extra observation of sounding balloon is tested.The analyzed fields and model forecasts of assimilating dense sounding data and the routine data are compared.Results show less root mean square error(RMSE) of water vapor by utilizing extra sounding data and the circulation and humidity are more accurate,according to the real atmosphere.And the forecast of location and magnitude of rainstorm of sensible experiment... |
