A Basis for Improving Numerical Forecasting in the Gulf Area by Assimilating Doppler Radar Radial Winds
3D-Var Data Assimilation Doppler Winds Errors NWP
font style='font-size:12px;'>
2013/3/6
An approach to assimilate Doppler radar radial winds into a high resolution Numerical Weather Prediction (NWP) model using 3D-Var system is described. We discuss the types of errors that occur in rada...
