A high resolution atmosphere-ocean coupled model has been developed in order to improve a Global Warming simulation. Based on preliminary experiments, it was decided that an atmospheric component is T106 global spectral model with 56 levels and an ocean component is 1/4 ° 1/6 ° grid point mode with 46 levels. A land surface model (MATSUSIRO) and a run-off model are incorporated. Corresponding to the increase in horizontal and vertical resolution, subroutines for physical processes are reexamined. Various options have been examined and final specification of the model was decided. Coupling between atmosphere component and ocean component is done through MPMD (Multiple Program and Multiple Data) algorithm. 10 nodes in the Earth Simulator (ES) are allocated to the atmospheric component and 76 nodes are allocated to the oceanic component. The version 0 of the coupled model was completed in 2003 and 40 year control run was conducted, and 1% increase of CO2 run was also conduced for 40 years. Simulation of atmospheric and oceanic phenomena was improved at many respects. It is suggested that a regional climate change may be achieved.
