Flow Analysis in the Pacific Ocean Using Data Assimilation System

Abstract

To elucidate the ocean current in connection with global warming and to prevent marine disaster and pollution problems, development of the ocean circulation model in the North Pacific Ocean has been called for. Numerical analyses were conducted in the Pacific Ocean areas to examine the effectiveness of data assimilations on circulation flow systems.
The results of analysis indicate a high reproducibility as compared with the existing data on surface current. The results by tracking water particles could approximately reproduce the tracking of Algos-buoys which was carried out in the past.
