A volume of air that has same temperature and moisture characteristics. Air masses from when air remains over relatively fat terrain with uniform surface characteristics for an extended period of time. Parcel of air sitting over the yukon, everyday it will get colder as radiation goes out to space and no sun comes back in --> very cold air mass. Cool oceanic regions such as the north atlantic and north pacific. Deserts such as the sahara and the american southwest desert. Air masses are generally classified by their temperature as.

Air masses are generally separated by the jetstream. Jetstream are strongest when there is a contrast ex.
