Abstract

A series of numerical experiments for the global ocean circulation were conducted using different grid-resolution ocean circulation models based on GFDL MOM4p1-SIS (coupled sea ice model). Both the two global circulation models with 1 degree x 1 degree resolution(GCM_1) and 0.5 degreex 0.5 degree resolution(GCM_05) adopted the same numerical schemes in the major model physics(i.e., psom tracer advection scheme, GM isopycnal mixing scheme, kpp vertical diffusion scheme, pressure-coordinate scheme) together with the same CORE surface forcing dataset except the surface thermal boundary condition and background vertical mixing. Differences in the distributions of temperature, salinity, sea surface height, ocean circulation and sea ice (thickness and concentration) are analyzed from the long-term integrations for the different model configurations.egree x 1 degree resolution(GCM_1) and 0.5 degreex 0.5 degree resolution(GCM_05) adopted the same numerical schemes in the major model physics(i.e., psom tracer advection scheme, GM isopycnal mixing scheme, kpp vertical diffusion scheme, pressure-coordinate scheme) together with the same CORE surface forcing dataset except the surface thermal boundary condition and background vertical mixing.
