A Nemeric Simulation Research Under The Condition Of Non-Sideboundary Of Variational Data Assimilation

This article shows the latest evolvement about four dimension assimilation of numeric weather forecasting in the domestic andoverseas, and a new method for assimilation--non-sideboundarycondition is emphasized. In this numeric experiment, adjoint code is introduced into the method for variational assimilation, which brings forward a new way for predicting the primitive field. this way' s feasibility is provedin theory and numeric research. the experimental result shows that the result of variational assimilation from the method is explicitly improved for the primitive field...
