Ocean Sciences session on Variability of convection & ocean-ice-atmosphere interactions in the high-latitudes

Veneziani, Milena
We are pleased to announce this OS session (HE012) on modeling & observational studies of variability of high-latitude convection and ocean, sea-ice, atmosphere interactions.
Conveners: Milena Veneziani, Carolina Dufour, Kent Moore, and Kjetil VĂ¥ge
Abstract submission deadline: September 11.

HE012 - Variability of high latitude ocean/sea-ice/atmosphere interactions and associated convection in a changing climate
Exchanges of heat, mass, and momentum across the air-sea interface impact the ocean and atmosphere and their interactions within the coupled climate system. In polar regions, these exchanges are significantly enhanced due to large air-sea temperature differences and high wind speeds, and are modulated by sea-ice. Such exchanges contribute in particular to water mass formation and deep convection that in turn impact physical and biogeochemical conditions throughout the world oceans. Because high latitude air-sea-ice interactions involve a complex interplay of processes at the interface between ocean, sea-ice, and atmosphere, many questions remain on the drivers of their temporal and spatial= variability. As more observations of high latitude regions are now available and resolution of numerical models is refined, progress can be made towards a better understanding of air-sea-ice interaction processes, their variability and impacts. In this session, we invite contributions that report on recent progress towards investigating high latitude air-sea-ice interface processes and their impacts on the local ocean, atmosphere, and sea-ice, as well as the larger coupled climate system, using observations, models or both. Contributions that address coastal or open-ocean deep convection in the Southern Ocean, subpolar North Atlantic, and Arctic are particularly welcome. We also invite studies that examine the impact of convection on the uptake of biogeochemical tracers.
