Persistent shift of the Arctic polar vortex towards the Eurasian continent in recent decades

The Arctic winter polar vortex has weakened in recent years: this study shows that there has also been a shift in the location of the vortex towards Eurasia. This is related to cryospheric changes, with implications for mid-latitude weather.
