| Research Abstract |
This study investigated the influence of the oceanic front along the Kuroshio Current to the global atmosphere in the cold seasons by developing a brand-new climate model, say two-way nesting model. The model was integrated with sharp or smoothed sea surface temperatures given in the models for enough time to take stable statistics. The result revealed a significant signal of precipitation around the oceanic fronts and the corresponding atmospheric response. A prominent distortion was found in the climatological background flow in the long-time integration of the two-way nesting model, however.
