This study describes the projection of sudden recovery from hypoxia in Tokyo Bay. Three different horizontal resolution of the Meteorological Research Institute Atmospheric General Circulation models (with a 20-km mesh resolution), and eight Coupled Model Intercomparison Project phase 3 (CMIP3 models) outputs were applied to project the occurrence of strong negative (south-west) winds, which enhance rapid recovery from hypoxia in the bay. South-west wind energy, KEw, was successfully reproduced in all models by using bias correction based on a cumulative distribution function from the present day (1980-1998). The MRI-AGCM3.1S with a 20-km mesh resolution suggested an increase in the number of days with the square of southwesterly winds>100 m2 s-2, but the other 10 models showed no significant difference in the future. As a result, it appears likely that recovery from hypoxia will not occur more frequently in the future if we assume that the other meteorological and hydrological conditions remain constant.
