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.</p>
