Abstract:
High resolution tracer transport model has been developed and it has applied to daily transport in this study. In this model, tracers were transported by the currents of the Japan Coastal Ocean Predictability Experiment (JCOPE) 2. By using this model, the distributions of dissolved inorganic carbon (DIC) and partial pressure of carbon dioxide (pCO2) over the Northwestern Pacific Ocean (NWPO) with daily time scale were obtained. Their distributions were obviously associated with the mesoscale eddies existing in the Kuroshio extension region; the mesoscale structures in concentration fields were shown. Besides, the CO2 gas exchange between atmosphere and ocean was calculated. Also, the results compared with the ship observation.
