Regionale Atmosphärenmodellierung über dem nördlichen Nordatlantik: das Letzte Glaziale Maximum

Erchinger, Enno B.

Regional atmospheric modelling results for the northern North Atlantic in the Last Glacial Maximum are presented. The forcing global modelling followed in most aspects the Paleoclimate Modelling Intercomparison Project boundary conditions. The regional modelling almost reproduce the forcing data, considering the monthly background circulation, the monthly variability of circulation and the surface-near wind. In addition, the regional model's higher resolution lead to the following improvements upon the forcing data: (1) in some cases precipitation over the Greenland-Iceland-Norway-Sea is more realistic; (2) more detailed katabatic winds were modelled and in the February experiments they were stronger; (3) partly orographic precipitation is stronger; (4) no spectral artefacts in the precipitation occur off the Norwegian coast.
