A Prograde Jet Driven by Rossby Waves RORY 0. R. Y. THOMPSON]Oceanography Department, Florida State University. Tallahassee, FL 32306(Manuscript received 4 December 1979, in final form 8 February 1980)ABSTRACTWaves are forced by moving sources and sinks of mass on a beta-plane with Ekman friction. Ifthemotion is retrograde and not too fast, these are Rossby waves with a nonzero Reynolds stress u'c'.This stress forces a meridion$ mass flux which builds up a pressure gradient to allow a

lead to significant irreversible transport. Since it is straightforward to calculate P y < 0 and there are a growing number of studies using this or related criteria, we sought to create a more comprehensive RWB climatology, with a view toward future quantification of transport based on RWB. RWB can occur in association with critical surface absorption of planetary wave activity in the stratosphere, equatorward of the polar night jet. Baldwin and Holton (1988) analyzed P y reversals on the

1. Introduction Satellite observations and reanalysis products show evidence of poleward shifts of the mean latitude of the extratropical storm tracks ( McCabe et al. 2001 ; Fyfe 2003 ; Bender et al. 2012 ) and jets ( Lee and Feldstein 2013 ). Similar jet shifts have also been identified in the ensemble of twenty-first-century climate simulations ( Yin 2005 ; Tsushima et al. 2006 ; Meehl et al. 2007 ; Barnes and Polvani 2013 ). Kushner et al. (2001) showed that CO 2 increases can drive

1. Introduction Stability theories have traditionally been applied to midlatitudinal atmospheric shear flows to understand extratropical cyclogenesis and forecast errors. In both cases, the interest lies mainly in the growth rate of the disturbances rather than in the propagation rate. Nevertheless, investigation of the structure of analysis and forecast errors in the Pacific jet shows that, on average, the speed of the peak of the error packet is close to the speed of the mean jet-level zonal

1. Introduction This is the second paper of a three part series on the use of Rossby wave chromatography (RWC; Held and Phillips 1987 ) to understand the variability of the midlatitude jet and its response to external forcing. In the first paper in this series, we describe our implementation of RWC in a linearized nondivergent barotropic model and compare the RWC model to the results from a full general circulation model (GCM; Lorenz 2014a, manuscript submitted to J. Atmos. Sci. , hereafter L
