Cover Story: At the cloud top of the Venus atmosphere, equatorial Kelvin waves have been observed and are considered to play an important role in super-rotation. We were able to reproduce the wave in a general circulation model (GCM) by conducting an observing system simulation experiment (OSSE) with the help of a data assimilation system. The synthetic horizontal winds of the Kelvin wave produced by the linear wave propagating model are assimilated at the cloud top (~70 km) in realistic conditions, assuming they are obtained from cloud tracking of ultraviolet images taken by the Akatsuki Venus orbiter. It is demonstrated using Eliassen–Palm fluxes that the reproduced Kelvin wave transports angular momentum and plays an important role in the magnitude and structure of super-rotation. View this paper
