Air masses
This document discusses air masses and their characteristics. It defines air masses as large bodies of air with similar temperature and humidity. It identifies the four main types of air masses - maritime, continental, tropical, and polar - and describes their source regions, conditions, and typical locations. The document also provides examples of specific air mass types and how they can be modified as they move over land or water.
