I am writing a fan-fiction (thus the world that my story is set in is not mine though some modifications can be done in accordance to my story's timeline and setting in relation to the canon universe) where at some point the characters travel to a moon (which has a breathable atmosphere) of the main planet.
I plan that this moon has a giant wall, reaching the Karman line of the atmosphere (it does not really matter how high this line is, after all clouds are usually way below that arbitrary line), surrounding the entire circumference from pole to pole, separating the visible side, barren and moon-like, from the "far side", Earth-like and thriving with life and a civilization.
I try imagining how this world looks like from space, seeing a sudden and abrupt separation between an Earth-like landscape with oceans and trees and a barren white/grey cratered land. However I have difficulty seeing how clouds would look like.
Since the moon is tidally locked then the clouds would look like diagonal stripes opposite of each other on both hemispheres, like this image: https://upload.wikimedia.org/wikipedia/commons/thumb/b/b9/TerraformedVenus.jpg/250px-TerraformedVenus.jpg
However, with a wall surrounding the planet from pole to pole (in other words surrounding an entire meridian), I find it hard to know how clouds can work or move in such a situation.
So how will the clouds look like from space, in terms of overall shape and their movement through the atmosphere, when there is a giant "meridian wall" that practically reaches the Karman line of the moon's atmosphere?
