The hydrological and energy cycles are examined using the Community Climate System Model version 3 (CCSM3) for two climates, the Last Glacial Maximum (LGM) and Present Day. CCSM3, developed at the National Center for Atmospheric Research, is a coupled global climate model that simulates the atmosphere, ocean, sea ice, and land surface interactions. The Last Glacial Maximum occurred 21 ka (21,000 yrs before present) and was the cold extreme of the last glacial period with maximum extent of ice in the Northern Hemisphere. During this period, external forcings (i.e. solar variations, greenhouse gases, etc.) were significantly different in comparison to present. The “Present Day” simulation discussed in this study uses forcings appropriate for conditions before industrialization (Pre-Industrial 1750 A.D.). This research focuses on the joint variability of the hydrological and energy cycles for the atmosphere and lower boundary and climate feedbacks associated with these changes at the Last Glacial Maximum.
