Mesoscale and Submesoscale Processes: Characterization, Dynamics, and Representation V

Submit an Abstract to this Session

Session ID#: 11469

Session Description:
Mesoscale and submesoscale features such as coherent eddies, fronts, jets, and striations are ubiquitous in the world ocean. These features contribute significantly to horizontal and vertical transport and mixing, and have important interactions with the larger and smaller scale circulations, as well as with the physical and biogeochemical components of the climate system. However many aspects of their structure, evolution, and impacts are not fully understood, and they remain poorly represented in large-scale models.

This unified session invites reports on theoretical, observational, and modeling studies on all topics relating to mesoscale and submesoscale phenomena such as eddies, fronts, and jets, and in particular on the following three themes:
(i) Detection, observation, and description of mesoscale and submesoscale features and their dynamics
(ii) Understanding mesoscale and submesoscale impacts, transport characteristics, and interactions with the circulation, as well as surface, biogeochemical and climate processes
(iii) Representing mesoscale and submesoscale processes in numerical models, and model sensitivity to such parameterizations.

We aim to showcase novel methods and results that make the most of the rapidly growing sophistication of the datasets and models available, with the hope of inspiring an improved understanding of eddy processes and their role in the global climate system.
