Air has mass • An air mass is a body of air that is uniform in temperature, humidity and pressure. • How do we know air has mass? Air masses are named by where they form: • Where would a cold dry air mass form? • Where would a warm and humid air mass?

Classifying air masses • Air masses are classified based on the surface over which they form, and their overall temperature – There are 4 basic types: • • Continental polar = dry and cool Continental tropical = dry and warm/hot Maritime polar = humid and cool Maritime tropical = humid and warm/hot
