Simulation of Regional Climate Using a Limited Area Model Nested in a General Circulation Model

摘要: Abstract A Limited Area Model (LAM) is nested in a General Circulation (GCM) to simulate the January climate over western United States. In nesting procedure, GCM output used provide initial and lateral atmospheric boundary conditions necessary drive LAM. this approach, realistic large-scale behavior an area of interest LAM describe effect local, sub-GCM grid scale forcings (such as those induced by complex States topography) on regional patterns climatic variables. Two versions National Center for Atmospheric Research (NCAR) Community Climate [the seasonal CCM1 at 4.5° × 7.5° (R15) 2.89° (T42) latitude-longitude resolution] are version Pennsylvania State University/NCAR mesoscale model (MM4 60 km resolution), which includes sophisticated soil hydrology calculations. The climatology region analyzed...
