2002-2003 Is on of the analog years we are highlighting. The biggest problem with this analog is the QBO values are reversed. We are going to be coming down from a strong negative phase into positive territory (possibly). 2002-2003 saw a shift from positive to negative in that winter.
Another analog year being used is 2009-2010. Once again the QBO values do not match up but the negative values in this particular led to some impressive high latitude blocking. We expect this to be somewhat similar to the winter of 2012-2013.
