Annular modes of the troposphere and stratosphere

P. J. Kushner

A pedagogical review of the phenomenology, dynamics, and simulation of the annular modes is presented. First, the manner in which the annular modes capture the principal features of variability in the zonal mean circulation of the extratropical stratosphere and troposphere is demonstrated. Next, elementary ideas about annular mode dynamics, in particular, the distinct eddy mean-flow interactions that govern the modes in the troposphere and stratosphere, are introduced. The review concludes with a discussion of the representation of the annular modes in simplified and comprehensive general circulation models in the context of stratosphere-troposphere interactions in intraseasonal variability and climate change.
