Gianluca Meneghello
Arctic Dynamics Workshop
Monday and Tuesday 18th-19th November, 2019 MIT, Whitaker College, 4th floor, Room E25-401 (directions) For information please contact mgl@mit.edu
The presence of sea-ice at the surface of the Arctic Ocean strongly reflects incoming radiation and mediates the effect of the winds driving the circulation below. As the Arctic warms and the ice becomes less extensive and more mobile, its buffering effect will change and the Arctic will move in to a new regime. The aim of this workshop is to survey key theoretical ideas, identify knowledge gaps and stimulate further advances in our understanding of Arctic Ocean change.
