Superrotating winds occur in a handful of celestial bodies in our solar system. We are investigating the phenomenon on a full topographic model of Venus using the EPIC atmospheric model. The model is forced with the same Newtonian cooling scheme recently used by Lee, Lewis, and Read (2005, Adv. Space Res. 36, 2142-2145) to spin up a model of Venus's atmosphere without topography. We reproduce their results with our model, which is developed independently and uses a different vertical coordinate. Both groups use a horizontal resolution of 5°, which is dictated by the need for reasonable computer runtime and is not a claim of numerical convergence. We find that the addition of topography substantially changes end state of the model's spin up: the magnitude of the superrotation is diminished from 55 ms-1 to 35 ms-1. In addition, topography induces standing eddies and prevailing winds at the surface, and a temperature anomaly associated with Ishtar Terra in the upper atmosphere near the north pole.
This research is funded by the NSF Planetary Astronomy Program and NASA Planetary Atmospheres Program.
