C34B:
Sea Ice–Ocean–Atmosphere Interactions in the “New” Arctic and Southern Oceans I


Submit an Abstract to this Session


Session ID#: 60453

Session Description:
Record low sea-ice extent is currently observed in both the Arctic and Antarctic, variability that is unprecedented in the satellite record. Warming ocean temperatures, changes in atmospheric circulation patterns, and frequency of synoptic systems contribute to this variability. To predict future changes in sea ice it is necessary to understand the complex and coupled interactions between ice, ocean, atmosphere, and land. Improved representation of coupled processes and feedbacks is expected to advance predictive skill of polar weather and climate models, and linkages with lower latitudes. Conveners solicit papers on observational, theoretical and numerical investigations that advance a system level understanding of processes that affect sea ice extent and thickness in the Arctic and Southern Oceans by studying the interaction between ice and at least one other component of the polar system (ocean, ecosystems, atmosphere, land). This session will feature 5-minute discussion periods after talks to facilitate dialog on overlapping issues.
