13: 1) March 2013 was exceptionally cold over most of Europe and was the second coldest March in the UK since 1910. The cold temperature anomalies also extended over large portions of North America and Asia. This cold event lasted for about a month, and was associated with a negative phase of the North Atlantic Oscillation (NAO).  The attached paper, published in Meteoworld (April 2014 issue), describes an investigation on its sub-seasonal predictability and causality. CLOSED
