Abstract
The intensity and stationarity of explosively developing extratropical cyclones are investingated utilizeing the European Centre for Medium-Range Weather Forcasts (ECMWF) Re-Analysis (ERA-40) and the three models on phase 3 of the Coupled Model Intercomparison Project (CMIP3). As the future climate (A1B scenario), we forcus on decades during which the global-mean temperature increases by 2 °C in each models. Explosively developing extratropical cyclones whose central pressures are less than 960 hPa and moving velocities are less than 30 km/h in Japan and its surroundings are located over the Sea of Okhotsk off the coast of Northeastern Hokkaido. When these cyclones exist, atmospheric blocking tends to locate over the North of Japan.
