1. Introduction Winds in the middle atmosphere have now been observed for more than half a century, but the debate about their interpretation continues. Points of contention include the resolution of the wind into various components—global means, tides, gravity waves, and turbulence—and the relative importance of nonlinear dynamics in the observed structures. Recently, considerable attention has been given to the small-scale vertical structure of the wind because spectra obtained at various

troposphere radiates GWs with phase propagation into all horizontal directions, mainly westward (eastward) GWs will reach the winter (summer) mesosphere, where they break and deposit their westward (eastward) momentum (e.g., Lindzen 1981 ). Accordingly, a stronger and less variable eastward zonal wind in the winter middle atmosphere is more favorable for vertical propagation of westward GWs. Since the southern winter polar night jet is, on average, much stronger and less variable than its Northern

On the General Circulation of the Atmosphere in Middle Latitudes

A Preliminary Summary Report on Certain Investigations Conducted at the University of Chicago during the Academic Year 1946–1947

Staff Members of the Department of Meteorology of the University of Chicago

SUMMARY

A synoptic, theoretical and experimental study of the general circulation of the atmosphere in middle latitudes and of the major perturbations superimposed on this circulation pattern was conducted by a group of research workers at the University of Chicago during the academic year 1946–1947. The principal results of these investigations are summarized below in a series of specific statements. Not all of these conclusions are new, and some require further verification, but it is hoped that they may be of some use as a starting point for further discussions and investigations of the general circulation of the atmosphere.
