Inter-Relations between the Arctic Sea Ice and the General Circulation of the Atmosphere
Abstract Satellite imagery has substantially improved the quality of sea-ice observation over the last decades. Therefore, for a 25 year period, a statistical study based on the monthly Arctic sea-ice data and the monthly mean 700 mbar maps of the Northern Hemisphere was carried out to establish the...

Abstract Satellite imagery has substantially improved the quality of sea-ice observation over the last decades.

It was found that sea-ice conditions have two opposing effects on the zonal circulation intensity, depending on the season.
