Numerical simulation of the climate 9000 years ago
9000年前古气候的数值模拟研究

The January and July climates 9000 years ago was simulated with the IAP AGCM. The seven percent more solar radiation than present absorbed in the Northern Hemisphere summer caused by the orbital parameter changes makes the earth's surface temperature higher, especially in high latitude region. The enhanced landsea contrasts cause a stronger summer monsoon, and the precipitation in the monsoon region is also reinforced. The Northern Hemisphere winter temperature is lowered by the weaker absorption of solar radiation. These results qualitatively agree with palaocJimatic evidences. And finally, the careful comparisons with other modeling results and further discussions are made in this paper.
