Habitable Venus

[The Astronomer]

On slow rotation, some say a Venus rotating close to Earth's rate would not be habitable due to the lack of cloud formation on the dayside to reflect sunlight, which is twice as strong. A slow-rotating Venus would still have the cloud formation which is helpful.

I have to wonder about that. At Earth-like levels of illumination and 24-hour rotation, there's plenty of time to develop large clouds. It's a daily cycle in Florida during the summer: clouds boil up from water throughout the day, then rain out in the evening. With twice the sunlight, you should be able to get more water into the air in less time. However, I'm not a meteorologist.

Oh, yeah I worded it wrong. The idea is, the winds on fast-rotating worlds would blow clouds away, leaving less cloud coverage than worlds with slow rotation, where milder winds allow more clouds to pile up. Although I do imagine that at some point the slow rotation is going to heat the subsurface point sufficiently to cause winds similar to very slow-rotating tidally-locked worlds. I have no clue on this one.
