  1. Yes, fluid dynamics is a complex subject and one which does not come into the undergraduate physics syllabus. Also, meteorology is a chaotic process as was discovered some years ago.
  2. Exactly - you have basically just repeated what I said. But if the air continues to rise I would think that it would carry the cloud up with it but that never seems to happen. It's a point which the textbooks I have read have not mentioned, but that happens in textbooks in many subjects - they all just repeat the same things. I call it "tramline thinking", where everybody just repeats what they hear from other people.
  3. If you have a meteorology degree maybe you can answer my question!
  4. When a cloud forms on a rising column of moist air, why does the cloud always remain at that height and stop moving? Presumably the air, now dry, keeps on rising for a time, because I see no reason why it would stop at that height just because the moisture has condensed out. But if the air does continue to rise, why doesn't it carry the cloud up with it? I have a physics degree but I have never studied meteorology and it seems to me that clouds are odd things - almost a fourth state of matter to go with solid, liquid and gas.
