英文摘要Glaciers over the Tibetan Plateau and surrounding regions during the Last Glacial Maximum (LGM) were much more extensive than during the preindustrial period (PI). The climate impact of such glacial expansion is studied here using the Community Atmosphere Model, version 4 (CAM4). To cover the range of uncertainty in glacier area during the LGM, the following three values are tested: 0.35 x 10(6), 0.53 x 10(6), and 0.70 x 10(6) km(2). The added glacier is distributed approximately equally over the Pamir region and the Himalayas. If 0.70 x 10(6) km(2) is used, the annual mean surface temperature of the glaciated regions would be cooled by similar to 3.5 degrees C. The annual mean precipitation would be reduced by 0.2 mm day(-1) (10%) and 2.5 mm day(-1) (24%) over the Pamir region and Himalayas, respectively. The surface mass balance (SMB) of the glaciers changes by 0.55 m yr(-1) (280%) and 20.32 m yr(-1) (220%) over the two regions, respectively. The changes in SMB remain large (0.29 and 20.13 m yr(-1)), even if the area of the Tibetan glacier were 0.35x10(6) km(2). Therefore, based on the results of this particular model, the expansion of glaciers can either enhance or slow the glacial growth. Moreover, the expansion of glaciers over the Himalayas reduces summer precipitation in central and northern China by similar to 0.5 mm day(-1) and increases summer precipitation in southern Asia by similar to 0.6 mm day(-1). The expansion of glaciers over the Pamir region has a negligible influence on the precipitation in these monsoonal regions, which is likely due to its large distance from the main monsoonal regions.
