Influence of the Scandinavian ice on the climate conditions of east plain European evidenced from the numerical simulation project PMIP II
In this paper results of climate simulation in East-European Plain (EEP) by coupled climate models (which take part in project PMIP II (Paleoclimate Modeling Intercomparison Project)) are tested for different climatic periods (pre-industrial, Last Glacial Maximum (LGM)). The main parameters for comp...
