Inter-Decadal Variations of Atmospheric Circulation Part II: GCM Simulation Study
摘要
Abstract
Similar to numerical simulations with atmospheric global circulation models (AGCM) in the Atmospheric Model Inter-comparison Plan (AMIP), an atmospheric global circulation model is introduced to make 43 years integration by monthly observed sea surface temperatures from 1950 to 1993. We use the long-time series to discuss the inter-decadal variations of the atmospheric circulation, mainly focusing on the three key oscillations and principal circulation systems in the tropics and the Northern Hemisphere, such as Southern Oscillation (SO), Pacific-North Americal pattern (PAN), though in East Asia at 500 hPa. The results strikingly show that the inter-decadal variations, including 10-20 and more than 30 years quasi-periods oscillations are very clear. The simulation results agree with observations quite well. We also analyze the precipitation in the eastern China with the simulation data, and obtain the notable inter-decadal variations, including the climate jump in the 1960's. At the same time, the above features correspond with the variations of the atmospheric circulation in East Asia very well. Above all, we can use the GCM simulation data to investigate not only the seasonal and inter-annual variations of the amtospheric circulation and climate, but the inter-decadal virations as well.关键词
