Recent studies have revealed strong interactions between resolvedRossby wave and parameterized gravity wave driving in stratosphere-resolving atmospheric models. Perturbations to the parameterized wave driving are often compensated by opposite changes in the resolved wave driving, leading to ambiguity in the relative roles of these waves in driving the Brewer–Dobson circulation. Building on pre...

Abstract. Ensemble simulation of the atmospheric general circulation at altitudes up to lower thermosphere is performed using 3-D nonlinear mechanistic numerical model MUAM. The residual mean meridional (RMC), which superposition Eulerian and wave-induced eddy components, calculated for boreal winter. Changes in vertical RMC velocity components are analysed different stages a simulated composit...

This paper examines the nature and robustness of internal stratospheric variability, namely the variability resulting from the internal dynamics of the stratosphere itself, as opposed to that forced by external sources such as the natural variability of the free troposphere. Internal stratospheric variability arises from the competing actions of radiative forcing, which under perpetual winter c...
