Arctic-Mid-Latitude Linkages in a Nonlinear Quasi-Geostrophic Atmospheric Model
A quasi-geostrophic three-level T63 model of the wintertime atmospheric circulation of the Northern Hemisphere has been applied to investigate the impact of Arctic amplification (increase in surface air temperatures and loss of Arctic sea ice during the last 15 years) on the mid-latitude large-scale...
