A diagnostic model for equatorial wave disturbances. The role of vertical shear of the mean zonal wind

Abstract

The model diagnoses the atmospheric perturbation due to a heating pattern of specified zonal wavenumber, frequency, and distribution in the meridional plane. Computations of the model show that meridional wind field has maxima in the upper and lower troposphere the precipitation occurs to the east of the surface trough, but with easterly shear the precipitation zone is west of the trough.
