Appears in collection : 2026 - T2 - WS1 - Vortices and vorticity in geophysical flows

Jets and Superrotation are ubiquitous features in some, but not all, planetary atmospheres. In particular superrotation occurs in slowly rotating terrestrial atmospheres (like Venus), in rapidly rotating gas giants (like Jupiter) and in some exoplanets. In this talk I'll discuss the various mechanisms giving rise to superrotation and their connection to potential vorticity.
