Scientific paper

The dynamics of linear and nonlinear, large-scale disturbances generated in the stratosphere by a localized perturbation in the troposphere are studied and compared. The perturbation is applied at the lower boundary of a primitive equation model of the stratosphere and mesosphere. The simulations are contrasted with an idealized theoretical model of a nonlinear critical layer. It is suggested that regarding the troposphere as a wavemaker forcing changes in the stratosphere according to the tenets of wave, mean-flow theory is an oversimplification. It is found that, preceding a major warming, the flow is asymmetric about any axis and strong warmings develop through the nonlinear interaction of large, deep vortices associated with a tropospheric asymmetry. Associated changes in zonal mean winds give the appearance of distinct minor and major warmings, though a synoptic view allows systematic changes to be seen which caution against dividing the evolution into separate events.
