I would like to know what would happen with the atmosphere of Venus when it gets tidally locked, i.e. when one side would perpetually face the Sun.
Probably a thermal low would be at the subsolar region then.

At the surface Venus has an atmospheric pressure of 92 atm. and a temperature of 462$⁰$ C.

Are there General Circulation Models or Global Climate Models that can handle such input parameters ?

If so, are there GCM users (groups, universities etc.) who could run a tidally locked Venus simulation ?

    $\begingroup$ @BarryCarter The feeling a few years ago was that planetary atmospheres are on-topic here because they're on-topic at AGU/EGU. When it veers into worldbuilding/fiction we tend to close. $\endgroup$ – Deditos Nov 23 '19 at 19:49
  • $\begingroup$ I've retraced my close vote. My thought was that Venus is so different from Earth, Earth Science can't help here. We might be able to say something about Mars, because that's more similar to Earth, though, again, not really that much. $\endgroup$ – user967 Nov 23 '19 at 19:51
  • $\begingroup$ A tidally locked Venus would be no different on the surface than current Venus: The atmosphere is so thick and the winds are superrotating, which causes heat redistribution to be very efficient, and hence, Venus is horizontally isothermal on the surface. Tidal locking won't change that. $\endgroup$ – AtmosphericPrisonEscape Nov 24 '19 at 0:51

I'm not sure of their current status, but I read some papers based on these models a few years ago:

It looks like the introduction of Yamamoto et al (2019) has a more up-to-date summary of the current set of models, and there's quite a healthy selection from groups around the world.

  • $\begingroup$ Actually i should have asked for a tidally locked Venus model, but you already answered the original question, thank you ! $\endgroup$ – Cornelis in space Nov 23 '19 at 22:35
