Which effect amplifies polar jet stream displacement when Arctic sea ice diminishes?

💡 Explanation

A reduced sea ice cover enhances the latitudinal temperature gradient over high latitudes, therefore increasing gradients strengthens the Polar vortex due to thermal wind balance, rather than stability disruptions which would result in alternative outcomes.
