Abstract:
In the framework of the Paleoclimate Modelling Intercomparison Project
(PMIP), simulations of the Last Glacial Maximum (LGM) have- been performed. More than 10 different atmospheric general circulation models (AGCMs) have
been used with the same boundary conditions: sea-surface temperatures prescribed by CLIMAP (1981), ice-sheet
reconstruction provided by Peltier (1994), change in insolation, and reduced CO 2 content.
One of the major questions is to investigate whether the simulations of the LGM are in equilibrium with the prescribed ice-sheet reconstruction. To answer this question, we have used two different
approaches. First, we analyze the results of a sel of LGM simulations performed with different versions of the Laboratoire de Meteorolo-gie
Dynamique (LMD) AGCM and study the hydrologic and snow- budgets over the Laurcntide and Fennoscandian ice sheets. Second, we use the AGCM outputs to
force an ice-sheet model in order to investigate its ability to maintain the ice sheets as reconstructed by CLIMAP
(1981) or Peltier (1994).
