PO001:
Advances in understanding ocean eddies and their interactions with the atmosphere


Session ID#: 29697

Session Description:
The ocean, like the atmosphere, is a fundamentally turbulent system. As such, intense nonlinear interactions give rise to fine-scale structures, such as eddies, fronts, jets and filaments, that are of critical importance for the ocean circulation. These features are ubiquitous, and they have been recognized as key contributors to ocean transport of properties. Their energy generally exceeds that of the mean flow by an order of magnitude or more. Mounting evidence points to intense interactions, especially in the extratropics, between the atmosphere and the ocean on the scales of ocean eddies, which are much smaller than atmospheric synoptic scales. These interactions can have an important impact on the entire troposphere, affecting the positions of jet streams and their low-frequency variability, and they are likely a key-missing element in closing the budget of Earth’s energy imbalance. Theoretical understanding of eddy dynamics, especially in terms of air-sea interactions, however, remains incomplete. This represents an acute weakness in our present understanding of coupled ocean-atmosphere dynamics and its role in shaping variability and change of Earth’s climate.

We encourage submissions of abstracts describing new research findings, from observations and numerical modeling, on ocean mesoscale eddies, including their interactions with and feedbacks from the atmosphere.
