What is the classification for a warm air mass originating over land?

The classification for a warm air mass originating over land is indeed cT, which stands for continental Tropical. This type of air mass is characterized by being warm and dry because it forms over land in low-latitude regions where the sunlight heats the ground more efficiently than over water. As the land warms, the air above it also warms up, creating a warm air mass. The 'continental' aspect indicates its land origin, while 'tropical' refers to the warm temperatures typically associated with air masses formed in lower latitudes.

In contrast, other classifications denote different characteristics. For example, mT (maritime Tropical) refers to warm, moist air that originates over oceans, while cP (continental Polar) is associated with cold, dry air masses that come from colder land areas. Lastly, mP (maritime Polar) describes cool, moist air masses originating over colder oceans. Understanding these classifications is crucial for meteorology as they help predict weather patterns and climate behaviors significantly influenced by air mass characteristics.
