Impacts of regional Arctic sea ice loss and the role of QBO
Climate model studies investigating the role of Arctic sea ice loss in future projections have shown a wide range of possible mid-latitude responses in the northern hemisphere, beyond the more robust local thermodynamic warming response. We use new atmosphere-only experiments from the Polar-Amplific...

Climate model studies investigating the role of Arctic sea ice loss in future projections have shown a wide range of possible mid-latitude responses in the northern hemisphere, beyond the more robust local thermodynamic warming response.

The multi-model winter response to reduced Arctic Sea Ice adds further evidence of an equatorward shift of the tropospheric jet and a shift towards the negative phase of the North Atlantic Oscillation.
