摘要: AbstractThe authors present results for simulated climate and change from a newly developed high-resolution global model [Geophysical Fluid Dynamics Laboratory Climate Model version 2.5 (GFDL CM2.5)]. The GFDL CM2.5 has an atmospheric resolution of approximately 50 km in the horizontal, with 32 vertical levels. horizontal ocean ranges 28 tropics to 8 at high latitudes, This allows explicit simulation some mesoscale eddies ocean, particularly lower latitudes.Analyses are presented based on output 280-yr control simulation; also 140-yr which CO2 increases 1% yr−1 until doubling after 70 yr.Results compared CM2.1, somewhat similar physics but coarser resolution. shows marked improvement over many regions, especially tropics, including reduction double ITCZ i...
