CLIVAR Project
Study of the Atlantic thermohaline
circulation in a highly efficient global ocean-atmosphere model
Progress Report, February
2000
The MOM 3 ocean model has been implemented
in three global configurations with 2 degree, 4 degree and 5 degree resolution.
Preliminary ocean circulation results are shown in Fig. 1.

The CLIO sea ice model has been
coupled to MOM and is currently being tested. Preliminary results are presented
in Fig. 2.

Coupling of MOM/CLIO with the POTSDAM-2 atmosphere module is underway.
