“…As shown in several studies and mentioned above, in particular the synoptic-scale Rossby wave breaking drives not only most atmospheric teleconnection patterns (Feldstein, 2003;Benedict et al, 2004;Franzke et al, 2004;Riviere and Orlanski, 2007;Woollings et al, 2008;Franzke et al, 2011a) but also transitions between atmospheric flow regimes (Benedict et al, 2004;Franzke et al, 2004;Woollings et al, 2008;Riviere, 2010;Riviere et al, 2010;Franzke et al, 2011b).…”
