Interannual variability of European winter weather: the potential vorticity insight

Abstract
Consideration of well‐established teleconnection patterns account for only a moderate part of European winter variations. Here January interannual variability is examined from a potential vorticity perspective and this yields a reappraisal of the pattern structure and link to European winter weather. The influence of a novel hemispheric pattern in particular is detected. Copyright © 2001 Royal Meteorological Society.
