New insights on ocean eddies and their impacts
报告简介:
Mesoscale eddies are one of the most prominent and energetic physical phenomena in the world ocean, and thus have attracted a great deal of attention and research efforts over the last half of a century. Here we first briefly review the history of eddy studies, the important roles of eddies in ocean dynamics, and the hot topics in this research field. Then, based on observational data, numerical experiments and theoretical analysis, we report some recent progress on ocean eddy research, especially the new insights on the eddy’s abnormal structure and movement, the eddy-induced transport and mixing, and the impact of eddies on general ocean circulation. Finally, we discuss the long-standing challenge in observing the three-dimensional structure of submesoscale eddies, and provide a possible solution based on an intelligent swift ocean observing system.
