Winter 2010 ranks as the 13th coldest winter since 1949 over Europe, far behind the cold record of 1963 (−4.0°C, −2.9σ) despite comparable atmospheric dynamics indices. Winter 1963 indeed experienced the 3rd lowest NAOi since 1824 (Figure 1b), and the 2nd lowest NAO+ regime frequency (Figure 2e). However cold temperatures of winter 1963 seem caused by both NAO− and strong Scandinavian blockings, while NAO− largely dominates in winter 2010 (Figure 2). http://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2010GL044613#grl27398-bib-0010
