WebEarlier work of Manola et al. (2013) suggests that strong and narrow jets are 30 associated with high waveguidabilty, although their work does not suggest a mechanistic explanation. To the extent that the midlatitude background ﬂow represents an efﬁcient waveguide, this may lead to circumglobal Rossby WebAlthough it is well known that the persistence of extratropical jet shifts is enhanced by a positive eddy feedback, the dynamics of this feedback is still debated. Two types of mechanisms have been proposed: barotropic mechanisms rely on changes in upper-level propagation and baroclinic mechanisms rely on the coupling between barotropic and …
