Meridional Asymmetries in Large-Scale Atmospheric Dynamical Phenomena

Meridional asymmetry from the inclusion of meridional variation in the Coriolis parameter is shown to be a fundamental property of the higher-order dynamics of Eady edge waves. This asymmetry may be relevant to structural characteristics of observed atmospheric transients, particularly short waves propagating alone the extra-tropical dynamic tropopause. Balanced motions with incorporated higher-order beta effects are studied based on the mid-latitude channel geometry. Numerical model of freely decaying turbulence is investigated. Meridional asymmetries of the flow are revealed.
