Winter Lead Convection The Study of Environmental Arctic Change (SEARCH) and the Barrow Cabled Observatory Presentation at Science and Education Opportunities.
Examples Decreased sea level atmospheric pressure, Increased air temperature over most of the Arctic, More cyclonic ocean circulation and rising coastal sea level, Warmer Atlantic waters, Reduced sea ice cover, Warming of permafrost The physical changes of Unaami impact ecosystems and society. Complex of change appears related to a spin up of the Northern Hemisphere atmospheric Polar Vortex. Complex of Arctic change is a possible component of climate change. Motivates a program of long-term observations, analysis, and modeling

Winter Lead Convection
The Study of Environmental Arctic Change (SEARCH) and the Barrow
Cabled Observatory
Presentation at Science and Education Opportunities for an Arctic Cabled Seafloor Observatory
February 7-8, 2005
Jamie Morison Polar Science Center, University of Washington
Examples• Decreased sea level atmospheric pressure,• Increased air temperature over most of the Arctic, • More cyclonic ocean circulation and rising coastal sea level,• Warmer Atlantic waters, • Reduced sea ice cover,• Warming of permafrost• The physical changes of Unaami impact ecosystems and society.
Complex of change appears related to a spin up of the Northern Hemisphere atmospheric Polar Vortex.
Complex of Arctic change is a possible component of climate change.
Motivates a program of long-term observations, analysis, and modeling
