Abstract
The climate influence of the land ice that existed at 18k yr BP is investigated by use of a general circulation model of the atmosphere coupled with a static mixed layer ocean. In the Northern Hemisphere the tropospheric flow field is strongly influenced by the Laurentide ice sheet and features a split flow straddling the ice sheet, with a strong jet stream forming the southern branch. The 18k yr BP ice sheets have very little influence upon atmospheric temperature and SST in the S Hemisphere. Hydrologic changes in the model climate are also found, with statistically significant decreases in soil moisture occurring in a zone located to the south of the ice sheets in N America and Eurasia. -from Authors
