Abstract

In order to consider the effect of steric sea level change directly, we developed the regional version ocean circulation model (ReMOM) using the GFDL MOM version 4 which does not use the Boussinesq approximation. The GFDL CM2.1’s SRES A1B and B1 results from IPCC were used for the initial and boundary conditions in the northwestern Pacific. The sea surface temperature and sea surface height were increased by about 2oC and 30cm for SRES A1B, and about 1oC and 22 cm for SRES B1 after 100 years, respectively. East Sea was affected by steric effect more than Yellow Sea. It caused by the warmer Tsushima current passing the Korea strait due to global warming. The sea level rises by the direct steric effect were higher than by the indirect steric effect.
