Session 2B Polar Climate Variability and Change—Part I

Monday, 7 January 2019: 10:30 AM-12:00 PM
North 122BC (Phoenix Convention Center - West and North Buildings)
Host: 32nd Conference on Climate Variability and Change
Zhenxia Long, Bedford Institute of Oceanography, Dartmouth

We invite abstracts focusing on climate impacts on high latitude systems in northern and southern polar regions at both regional (e.g., Bering Sea, Beaufort Sea, Barents Sea, Labrador Sea) and broader spatial scales (e.g., Arctic Ocean and the Southern Ocean). We seek papers that evaluate climate impacts at time scales ranging from seasonal, decadal, to multi-decadal. Topics of particular interest include: (a) Seasonal time scales, for example, estimates of summer ice conditions in the Arctic (or Antarctic) and links to preceding winter and early spring atmosphere and ocean conditions; (b) The impacts of climate change on high latitude and Arctic or Southern Ocean storms and their impacts and feedbacks on the upper ocean; (c) The role of inertial gravity waves, mesoscale and sub-mesoscale eddies and related processes on mixed layer depths, vertical mixing, and on the ice edge and related ice conditions; (d) Estimates of climate and climate change on longer time scales, up to the next several decades, e.g. following IPCC scenarios; and (e) Climate impacts on high latitude ecosystems.
