A Simple Condensation Model for the H₂SO₄-H₂O Gas-Cloud System on Venus

Shao, Wencheng D.; Zhang, Xi; Cui, Jun +2 more

The current Venus climate is largely regulated by globally covered concentrated sulfuric acid clouds from binary condensation of sulfuric acid (H₂SO₄) and water (H₂O). To understand this complicated H₂SO₄-H₂O gas-cloud system, previous theoretical studies either adopted complicated …

Winds From the Visible (513 nm) Images Obtained by the Venus Monitoring Camera Onboard Venus Express

Ignatiev, N. I.; Zasova, L. V.; Titov, D. V. +4 more

We present more than 250,000 wind vectors derived from the visible (513 nm) images captured by the Venus Monitoring Camera (VMC) onboard ESA's Venus Express orbiter in the Southern hemisphere from 01 July 2007 to 29 January 2013. From comparison to the wind velocity derived from tracking of the descent probes, these measurements correspond to 60 ±…

Dynamical Effect on Static Stability of the Venus Atmosphere Simulated Using a General Circulation Model: A Comparison With Radio Occultation Measurements

Tellmann, Silvia; Pätzold, Martin; Imamura, Takeshi +10 more

Distributions of temperature and static stability in the Venus atmosphere consistent with recent radio occultation measurements are reproduced using a general circulation model. A low-stability layer is maintained at low- and mid-latitudes at 50-60 km altitude and is sandwiched by high- and moderate-stability layers extending above 60 and below 50…
