Air Masses And Fronts - Dslavsk.sites.luc.edu
Air Masses and Fronts Air We know that rising air cools, and if a parcel of air cools sufficiently, it will cool to its dew point and condense, initiating cloud formation. Since the warmer air glides up along the colder wedge, the warmer (usually moister) air is forced to rise, and condenses ... Read Full Source
