bluewave Posted October 18, 2012 Share Posted October 18, 2012 http://www.aoml.noaa...-D-12-00128.pdf The record-breaking U.S. tornado outbreaks in the spring of 2011 prompt the need to identify long-term climate signals that could potentially provide seasonal predictability for U.S. tornado outbreaks. Here we use both observations and model experiments to show that a positive phase Trans-Niño may be one such climate signal. Among the top ten extreme outbreak years during 1950-2010, seven years including the top three are identified with a strongly positive phase Trans-Niño. The number of intense tornadoes in April - May is nearly doubled during the top ten positive Trans-Niño years from that during ten neutral years.

andyhb Posted October 18, 2012 Share Posted October 18, 2012 Interesting article. Those figures clearly show why April 2011 was such a brutal tornadic month in the SE. Link to comment Share on other sites More sharing options...
