Numerical Experiments with the Coupled Ocean-Earth-Atmosphere Circulation Model and the Analysis of Decadal Variability of Its Main Physical Characteristic

Abstract

The statistical analysis of ensemble numerical experiments with a sample about 50 members of the Earth System Model outputs of the Max Planck Institute for Meteorology (MPI-ESM) from Hamburg, Germany is analyzed. The set of fifty initial conditions is set up and the model runs for 30 years were integrated from those conditions. The main model physical characteristics such as temperature, sear level and ice coverage are obtained and analyzed. Also, the most probable trajectories using the statistical ensemble Monte-Carlo scheme are investigated. The similarity of the model results with the natural tendencies is also shown. In particular, the specific properties of nonlinear equations are analyzed and discussed. Numerical calculations were carried out on the Lomonosov-2 supercomputer of Lomonosov Moscow State University and Mistral of DKRZ.
