the general meteorological conditions prevailing in a given area.

Q. If you are an asthmatic, is it better to live in a cold climate or hot climate?

A. Well, I'm not a doctor and I guess you should consult one cause each patient can get allergic asthma from different things but as an asthmatic I can tell you it's not necessarily has to do with cold/warm tough humidity and haziness are definitely important factors for some of us.
