So my planet is tidally locked, it constantly faces its star like the moon faces Earth. One side is completely frozen, the other is burning hot. There is an atmosphere that allows life, and people live on a thin ring that is at the right temperature to live.
I don't think life can emerge in that pattern, so assume the planet was once fit to allow life, and some undocumented event happened, making the planet stop spinning ("tidally locked" is more precise). Enough time has passed for the climate to stabilize completely (I'm talking in million years). The current population is descended from colonists who settled on the planet after the climate had stabilised.
How would the winds and oceans be affected? [edit: the part of the question about the winds has an answer] Can a complete water cycle function on such a planet ? Winds are greatly influenced by oceans, so how would they behave ?
Are there other things that would behave in a special way ?
Note : I didn't know abut the term "tidally locked", thank you. That's what I meant (I also mixed up "rotation" and "revolution"). The part about the wind currents has already been asked.
