英文摘要
The new data assimilation scheme is developed called as "ensemble 4-dimensional ariational method". This method can obtain the macroscopic gradients of cost function, hile the classical adjoint method obtains microscopic gradients. As a result, this new cheme can apply for strong nonlinear system. In this study, the efficiency of the new cheme is confirmed by the assimilation system for marine ecosystem model. In ddition, the new method is applied for atmosphere-ocean coupled models.
