Short summary
Here we use an Earth system model to simulate a long-lasting volcanic eruption at 65° N and investigate its impact on the stratospheric circulation. We show a polar vortex strengthening in winter 1, followed by a weakening in winters 2–3 due to surface cooling, where ocean–atmosphere interactions play a major role in the detected response. This weakening appears to trigger sudden stratospheric warming events that can cause severe cold spells throughout the Northern Hemisphere.
