This session seeks contributions characterizing the influences of mesoscale and submesoscale ocean-atmosphere coupling on Earthâs climate system based on observational, diagnostic, modeling and theoretical studies. The past two decades of observational and modeling studies have identified a fundamental regime of ocean-atmosphere coupling mediated by oceanic SST variability on scales smaller than 1000km. These studies demonstrate that the ocean eddy/front-forced variability of surface turbulent heat, momentum, and radiative fluxes drives an atmospheric response in both in the local atmospheric boundary layer and in the non-local downstream response influencing the development of the synoptic-scale weather systems. These studies have also indicated a significant feedback onto the ocean, influencing the gyre-scale circulation and ocean eddies. In addition, coupled air-sea processes driven by mesoscale and submesoscale variability impact the hydrologic cycle, and are thus important for understanding how climate change will affect terrestrial freshwater distributions.
Observing and modeling systems have evolved to capture mesoscale ocean variability, and are projected to provide new and better characterizations of ocean mesoscale and submesoscale variability. This session will focus on recent progress in this domain; specifically, the session invites contributions on:
1) satellite or observation-based diagnostic analyses;
2) theoretical or process-oriented investigations of the physical mechanisms of the coupling;
3) numerical modeling of the ocean, atmosphere or coupled system to explore the impacts of air-sea interaction on Earthâs climate; and
4) capabilities of current and future satellite and in situ observing systems for observing mesoscale and submesoscale ocean-atmosphere coupling.
