"Zarmina's World" -- Astronomer's Zeroing in On Habitable Extrasolars

Sure, but the temperature difference is static, the cold side air pressure will rise due to the air flowing their, until it cancels. Unless there is a big source of air on the hot side.

He's right - there are going to be constant wind speeds on tidally locked planets with atmospheres. Also remember that hot air rises, and what happens is that in the upper atmosphere air flows from the day side to the night side, where it cools down and sinks, and the pressure causes the cold air to flow from the night side to the day side at ground level. On many planets like that, it's supposed to actually keep the temperature relatively consistent across the planet that way.

The fact is that the geophysics of the situation is highly speculative.
