GFDL-NCAR/CCSM collaborations ongoing: Oceanic: 2 Climate Process Teams Atmospheric: Joint discussion group to be re-established – meeting in May at GFDL Both models contributing ~1/2 degree time-slice simulations to NARCCAP
200 km 50 km Annual mean precipitation: N. America and Europe
Other possible collaborations: Finite volume dynamical core: Cubed sphere version with non-hydrostatic option now in final stages of development, scalability studies underway – -- 200,100, and 50 km versions for coupling -- 20 km focused on tropical cyclone climatology, variability, sensitivity,
Are bilateral discussions/intercomparison useful in other areas? Aerosol modeling? Land surface vegetation feedbacks? Other Earth System Model components?
