| Research Abstract |
Physical mechanisms of temporal variations of the North Pacific subtropical front are clarified from an analysis of observations and numerical model results. On seasonal and interannual time scales, the variation of the front is caused by cyclonic surface wind system that forms just over the front, while for long-term changes due to global warming the front varies closely associated with changes of water masses located to the north of the front, showing that the mechanism is different with the time scales of the variations.
