International Workshop:Dynamics and Interactions of the Ocean and Atmosphere

Information

Summary  [May. 31, 2016 Updated]

The climate system, as a unified system of atmosphere and ocean, and its variability are of great concern to the society. The global cycle of energy, water and carbon is a key cross-cutting theme in climate research, which will be greatly improved by integrating knowledge of many different kinds of processes/phenomena/transports in the atmosphere and the ocean. This international workshop will provide an opportunity for atmospheric/oceanic scientists usually working on their own domains, where they can exchange ideas and gain new insights into each of the atmospheric and oceanic domains and/or into the coupled atmosphere-ocean system. To exchange knowledge among those scientists with different backgrounds, the workshop has a twofold focus. The first focus is on analogies and commonalities in atmosphere/ocean dynamics, whose understanding inspires advanced modellings and data analysis methods. The second focus is on interactions between the atmosphere and the ocean over a wide range of spatial and temporal scales, which are essential elements for better understanding of the coupled atmosphere-ocean system.
