摘要

We have developed a 4D-VAR global ocean data assimilation system which works efficiently on the earth simulator. The improvement of the computational efficiency has been made mainly by effective parallelization of the component codes and by a simple preconditioning of the gradient method. With this system we can reproduce dynamically consistent ocean states at high resolution which enable us to figure out the detailed dynamical features of ocean circulation and also gives us precise informations for ocean state prediction.
