Studies of atmospheric response to oceanic fronts and associated feedback onto the ocean using high-resolution analysis, observation and hierarchical models

为了探索大气对黑潮等洋流的响应，并了解大气响应进一步反馈到海洋的可能性，对东中国海的黑潮进行了研究。资料分析发现，ECS黑潮上空存在“深加热(大气响应)模”，在白云-梅雨季中期，伴随着显著的日雨和云量变化。数值研究表明，环流使日本周围的低压系统发展得更强，环流的季节性变暖在7月九州暴雨过程中起着重要作用。实船观测表明，冬季黑潮表层风减弱，对流有效势能在白云-梅雨季黑潮降水中起着重要作用。这些研究为迅速发展的中纬海气相互作用研究领域做出了重要贡献。

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.
