| Outline of Final Research Achievements |
In order to investigate the possible connection between the sea surface temperature (SST) front and the middle atmospheric circulations, we have conducted the high-resolution climate model simulations with horizontal and vertical resolutions of 60km and 300m, respectively. No gravity wave parameterization is included in this model. Two experiments with boundary condition of realistic SST and smoothed SST without SST fronts are conducted. The interannual variations of the middle atmospheric circulations are large and thus statistically significant differences of the circulations between these two experiments are not found. The possible connection could not be found from 20-year integrations of this high-resolution climate model.
