Abstract

A coupled atmosphere-ocean-vegetation general circulation model(AOVGCM) is used to investigate the climate of the early Holocene. It is found that the coupled AOVGCM can simulate the early Holocene climate successfully. In winter the averaged global surface temperature is 1.6 K less than today's, and 0.3 K less than today's in summer. The solar radiation has important effect on the high level atmospheric temperature, while the atmosphere temperature in the lower levels is sensitive to the land surface (for example ice sheets, vegetation and ocean, etc.). The simulated early-Holocene climate is drier than modern time in winter, but there are more precipitations in the tropical Pacific ocean some areas in the South Hemisphere. The climate in most areas in summer is wetter than today, especially in Asia and Africa monsoon areas where the monsoon is strong and the precipitation is abundant.
