Hi! Great post! Since October, most of Scandinavia has been covered in cold air and the cold anomalies for October-December only in this region has draw some attention. You said in the previous post that the polar vortex hasn't really coupled to the troposphere on a hemispheric scale (demonstrated by the painting drip). However, could it couple in a more regional sense and partly explain the persistent Scandinavian cold plume? For example if the vortex has been displaced more towards Europe than climatology?
