Abstract
The instability characteristics of three-dimensional flows typical of the Northern Hemisphere winter stratosphere and mesosphere are examined in a multi-level spherical quasi- geostrophic model. The basic-state distorted polar night jets are obtained from a numerical simulation of the sudden warming in a nonlinear spectral model. The results indicate that wave instability may be an important contributing factor in the sudden warming, which complements Matsuno's mechanism involving vertical wave propagation and wave-zonal flow interaction. -from Author
