Air masses are categorized and named primarily based on the region where they originate. This classification reflects the characteristics of the air mass, as it acquires specific temperature and moisture profiles from the area in which it forms. For instance, an air mass originating over warm tropical waters is likely to be warm and moist, while one forming over cold, snowy regions will be cold and dry. By identifying the source regions, meteorologists can predict the behavior and effects of air masses as they move into other regions, influencing weather patterns.

While other factors, such as temperature and moisture content, are certainly important in understanding the properties of an air mass, these attributes are derived from the original region. Thus, the categorization by origin is foundational. Choosing the region of origin provides a clearer insight into how the air mass will behave as it interacts with different environments, affecting local weather conditions.
