I have an ocean world in my science-fiction universe which is tidally-locked to its star. The planet is a tidally-detached moon from one the gas giants in the outer system, and orbits a red dwarf star. It receives about 66% of the solar radiation that earth receives from the sun, and its gravity is 26% that of earth. The atmospheric pressure is 0.8 bars, and the air is almost entirely composed of abiotic oxygen, (with a small percentage of carbon dioxide).
The planet is entirely covered in ocean, with no exposed landmasses.
How would the tidally-locked nature of this planet affect its cloud formations? What would they look like?
