| Research Abstract |
In order to explorer atmospheric responses to ocean currents such as the Kuroshio, and to know possibility that the atmospheric responses further feedback onto the ocean, researches are conducted with a focus on the Kuroshio in the East China Sea (ECS). Data analysis found "deep heating (atmospheric response) mode" over the Kuroshio in ECS accompanied by prominent diurnal rain and cloud variability in the middle of the Baiu-Meiyu season. Numerical studies showed that ECS causes stronger developments of low-pressure systems around Japan and that seasonal ECS warming plays an important role in heavy rain events over Kyushu in July. In-situ ship observations revealed weakening of surface winds over the Kuroshio in winter and showed an important role of convective available potential energy in precipitation over the Kuroshio in Baiu-Meiyu season. These studies are important contributions for rapidly developing research field of mid-latitude air-sea interaction.
