A hybrid nudging-ensemble Kalman filter approach to data assimilation. Part II: application in a shallow-water model

A hybrid nudging-ensemble Kalman filter (HNEnKF) data assimilation approach, explored in the Lorenz three-variable system in Part I, is tested in a two-dimensional shallow-water model for dynamic analysis and numerical weather prediction. The HNEnKF effectively combines the advantages of the ensembl...
