Planetary Wave Resonance Events

Caption

The number of planetary wave resonance events is shown as grey bars for each 4-year interval. While there used to be one or two events in a 4-year period, 2004-2007 saw three such events and 2008-2011 even five events. For comparison the red curve shows the change in Arctic temperature relative to that in the remainder of the Northern Hemisphere. Since 2000, the Arctic has warmed much faster than other latitudes.
