Abstract

The general circulation of slowly-rotating planets, such as Venus and Titan, differs from that observed in other planets. This regime is characterized by a prograde superrotating zonal flow which has a larger angular momentum than the underlying solid surface. It is required from transient eddies the convergence of angular momentum in the equatorial region in order to maintain such winds. However, the physical processes present in this phenomenon are still unclear. Therefore, this project aims to understand the main equatorial mechanisms in wave-mean flow interaction processes that drive the atmospheric superrotation. These analyses will asses the mechanism behind this phenomenon and will also enable an improvement of its simulation in numerical models. (AU)
