An Analytical Four‐Dimensional Ensemble‐Variational Data Assimilation Scheme
Abstract The usage of four‐dimensional variational (4DVar) scheme is limited by the static background error covariance and the adjoint model. In a hybrid frame of the four‐dimensional ensemble‐variational data assimilation scheme (4DEnVar), being able to avoid the tangent linear and adjoint models i...
