Atmospheric Control of the Surface Energy Budget
LONG-TERM GOAL: Understand how the atmosphere/ice system responds to changes in large-scale atmospheric forcing, including weather events, the seasonal cycle, and recent and historical decadal trends. OBJECTIVES: (1) Document the recent increased strength in the Arctic atmospheric polar vortex, term...

OBJECTIVES: (1) Document the recent increased strength in the Arctic atmospheric polar vortex, termed the Arctic Oscillation (AO). Special emphasis is on spatial co-variability. The AO is associated with increased wind speeds at middle altitudes (~ 500 mb), lower surface pressures, warmer temperatures at lower altitudes and colder stratospheric temperatures.

Sea ice is far from homogeneous on scales of 1-300 km. Major kinematic features are concentrated in long, narrow slip lines. In winter, surface fluxes are upward over thin ice and downward over thick ice. See also ADM002252.
