Abstract

We have developed a data assimilative regional ocean model in the northwestern Pacific based on the Modular Ocean Model Version 3. The model domain is from 115°E to 150°E and from 15°N to 52°N with 1/12° horizontal resolution. The numbers of grids are 420x444 horizontally and 40 vertically. The 3-dimensional variational assimilation routine has been fully coupled with the regional ocean model, and temperature profiles, and satellite-borne sea surface temperature and height have been assimilated. This regional ocean model will be coupled with the GFDL typhoon model. The analysis oceanic fields from the data assimilative ocean model will be displayed and the current systems in the Northwestern Pacific and marginal seas will be discussed.
