Simulation of the modern Arctic climate by the NCAR CCM1

Abstract

The NCAR CCM1's simulation of the modern arctic climate is evaluated by comparing a five-year seasonal cycle simulation with the ECMWF global analyses. The sea level pressure (SLP), storm tracks, vertical cross section of height, 500-hPa height, total energy budget, and moisture budget are analyzed to investigate the biases in the simulated arctic climate. The model has serious problems in simulating the present arctic climate, so its simulations of past and future climate change for this region are questionable. -from Authors
