Simple Venus upper atmosphere circulation paradigm. Here, MT = morning terminator; ET = evening terminator; SS-AS = stable subsolar to antisolar circulation cell driven by NIR and EUV heating; RSZ = retrograde superrotating zonal flow that seems to vary greatly over time; and He = helium tracer bulge. Adopted from Schubert et al. (2007).

The chemical evolution of an exoplanetary Venus-like atmosphere is dependent upon the ultraviolet to near ultraviolet (FUV-NUV) radiation ratio from the parent star, the balance between CO$_{2}$ photolysis and recombination via reactions that depend on the water abundance, and various catalytic chemical cycles. In this study, we use a three-dimensi...

... maximum MT and ET wind speed are tabulated in Table 2, and we see that the wind speed more than doubled for our VEN4 case and is remarkably fast at the ET. This can be understood by examining Figure 4 which shows the Venus upper atmosphere mean circulation paradigm adopted from Schubert et al. (2007). Previous observations show that Venus' upper atmosphere has two dominating circulation flow patterns (e.g., Bougher et al., 1997; Lellouch et al., 1997;Schubert et al., 2007;Brecht et al., 2021). ...

We present joint analysis of the UV (365 nm) images captured by the cameras on board ESA’s Venus Express and JAXA’s Akatsuki spacecraft. These observations enabled almost continuous characterization of the cloud top circulation over the longest period of time so far (2006–2021). More than 46,000 wind vectors were derived from tracking the UV cloud...
