摘要
用中科院大气物理研究所的9层大气环流模式IAP9LAGCM模拟了6000年前1月份和7月份我国的古气候,发现6000年前冬、夏季风均比现在要强,东亚季风气候更明显;在华夏文明发祥地的黄河、渭水流域,6000年前夏季降水比现在多,气温与现在相当,而冬季降水则与现在持平,气温甚至还略高。
The January and July climate of 6 000 years before present is simulated with the 9-level AGCM (Atmospheric General Circulation Model) of the IAP (Institute of Atmospheric Physics). The results indicate the intensity of winter and summer monsoon of 6 000 years ago present is stronger than the present, especially in east Asian monsoon area; and the summer precipitation in Chinese Yellow River and Wei River drainage basin is more than the present, and the summer temperature is equal. While the winter precipitation is nearly equal to the present, the winter temperature is higher.
