| Research Abstract |
A unified framework for energy diagnosis has been developed to investigate the effect of bottom topography on currents as well as the interaction between currents and waves in the ocean. This framework has been applied to investigate the effect of the bottom topography of the Drake Passage on the Antarctic Circumpolar Current and also to the effect of the bottom topography of the Lombok Strait on the generation of tidal internal waves with their interaction with the Indonesian Throughflow. The thickness-weighted-mean framework in the studies of mesoscale eddy parameterization has been applied to describe the effect of surface waves on the upper ocean currents.
