Abstract

In the study of radar wind field retrieval with variational assimilation method, the simple adjoint models have merits of simplifying calculation, saving time and improving efficiency. This paper studies wind field retrieval on levels of different height using the reflectivity advection equation as the control equation, proposes the parameterization method of sub-grid scale term which is related to the vertical motion. The flow pattern comparison and precision analysis with dual-Doppler radar have been made. Experiment results show this model could fully use the evolution information of reflectivity and effectively approximate to the real wind field.
