It has been proposed that a number of regional weather extremes in the Northern Hemisphere associated with blocked atmospheric circulation patterns may have been caused by '' ' quasiresonant amplification of Rossby waves ' '' . Examples include the 2013 European floods , the 2012 China floods , the 2010 Russian heat wave , the 2010 Pakistan floods and the 2003 European heat wave . Even taking global warming into account , the 2003 heat wave would have been highly unlikely without such a mechanism
