DESCRIPTION:This talk aims to\nshed light on the controls on the latitude 
 of Earth's jet streams\nand storm tracks. The relationship between the spe
 ed and the\nlatitude of the eddy-driven jet is investigated in a hierarchy
  of\ngeneral circulation models.\n\nA stirred barotropic model is used to 
 show that quasilinear wave-mean\nflow interaction theory predicts that fas
 ter jets should be shifted\npoleward.  The implications for mid-latitude c
 irculation changes in\nresponse to both forced climate change\, and tempor
 ary stratospheric\nwind-speed anomalies\, are discussed and investigated u
 sing primitive\nequation GCMs.
