Water cloud horizontal and vertical distributions. Water cloud Col. (a) in latitude vs. longitude coordinates and (b) tidally locked (TL) coordinates (b). Water cloud content vertical distribution (c) as a function of TL latitude (averaged over all TL longitudes). The plots were computed for an initially hot and steamy 2 R_⊕ planet (with a 10 bar H₂O + 1 bar N₂ atmosphere) synchronously rotating (fixed rotation period of 60 Earth days) around an M3 star, and forced to an ISR of 500 W m⁻² (simulation M3-YANG-1). The outputs were averaged over 250 Earth days. For reference, insolation is 340.5 W m⁻² on present-day Earth. Wind fields are superimposed on the plots. Winds are plotted at a pressure of ~50 Pa in panels a and b, and averaged over all TL longitudes in panel c.
