I am writing a science fiction story, and would like some help from the PH community. Details: There is a cylindrical space ship which is rotating to create artificial gravity. The cylinder has a circular radius of 10km and a length of 30km. The rotational period is 3 minutes and 20 seconds to produce 1g on the inside surface. It is filled with an atmosphere so that the pressure is 1 bar on the inside surface. One end (aft) of the cylinder is hotter due to the engines. The other end (forward) is kept cold to preserve an ice ablation shield. So the temperature inside the ship varies gradually from 0°F to 130°F. Questions: How will atmospheric pressure vary with altitude? How strong and what direction will the wind blow? What precipitation patterns would be expected? Thanks to anyone who can help!
