Outline of Final Research Achievements |
Dynamics of the “Western Pacific” pattern, a persistent pressure seesaw that modulates the East Asian winter monsoon has been revealed as a baroclinic dynamical mode. Evidence has been found that different dynamical regimes of the Kuroshio Extension can modulate surface wind and cloud/precipitation bands east of Japan. A new interpretation on the Southern Annular Mode has been proposed as a wobble of an eddy-driven westerly jet between the two states where the jet is under strong influence of oceanic fronts and not.
