Equatorial Planetary Waves in Shear: Part II

Abstract

Richard S. Lindzen{\textless}{BR} /{\textgreater}Dept. of Geophysical Sciences, The University of Chicago {60637The} general problem of the vertical propagation of equatorial waves through mean fields with vertical shear is solved analytically for all meridional wavenumbers using asymptotic multiple-scale methods. The results are used to show that the mixed gravity-Rossby wave is not the only easterly wave capable of penetrating the stratosphere, while the Kelvin wave is the only westerly wave capable of doing so. The results are also used to evaluate the effects of mean wind on diurnal tides.
