1. Introduction and motivation In this work we study how the basic-state wave propagation characteristics, and in particular the geometry of reflecting surfaces, affect the variability in the vertical structure of stratospheric planetary waves in a simple model and in observations of the Southern Hemisphere winter. The most common theory for stratospheric planetary waves is linear wave theory. Charney and Drazin (CD; 1961) were the first to treat stratospheric perturbations as vertically

that this instability is a necessary (though not sufficient) condition for superrotation in planetary atmospheres with axisymmetric forcing. In a related study, Polichtchouk and Cho (2016) found that superrotation can be generated in the presence of a weak equator-to-pole temperature gradient because of the reduction of breaking baroclinic waves from the midlatitudes and because of the presence of barotropic instability in the deep tropics. Polichtchouk and Cho also investigated the sensitivity
