Statistical relationship between the Northern Hemisphere sea ice and atmospheric circulation during wintertime
The wintertime relationship between the Northern Hemisphere sea-ice concentration, 500-hPa height, sea level pressure and 1000-500-hPa thickness is examined. The Northern Hemispheric sea ice extent exhibits a strong sensitivity to the climatic variation of atmospheric circulation anomalies. The sea-...
