Assimilation of Doppler Radar Velocity Observations with SVD-En3DVar Method.Part Ⅱ: Real Data Experiments
SVD-En3DVar方法同化多普勒雷达速度观测资料 II. 实际资料试验

In part I of this study(Xu et al.,2011),The ensemble-based 3DVar(three-dimensional variational technique) method with SVD(singular value decomposition) technique(SVD-En3DVar) is used for assimilation of the simulated radar velocity data and the results demonstrate that using the initial perturbation samples produced with 3DVar method in SVD-En3DVar can shorten the time interval of assimilation cycle and improve the short-term forecast of precipitation.In the current study the feasibility of using SVD-En3DVa...
