The stratospheric polar vortex forms each winter 10–50 km above the surface over the pole, and variations in its strength and position are known to influence the weather we experience. During winter 2018–2019, the Arctic polar vortex was highly variable – with both a sudden stratospheric warming and a strong vortex event. We discuss this unusual evolution of the vortex in terms of climatology and its impacts on surface weather patterns.
