Continental and maritime air masses can be divided into three more categories. These categories are based on the temperature of the surface over which they originated. What are these three temperature-based categories?

Three temperature-based categories are hot, cold and moderate. Continental cold (CTc), continental hot (CTh) and maritime cold (MTc), and maritime hot (MTh) are important.

Explanation:

Air mass refers to the presence of thick dense heavy air on the above of ground surface in stable condition. Where cold and warm air contrast that place is ideal for the creation of air mass. Air mass is of four types: continental, maritime, tropical and polar.

These air masses again divided into sub parts on the basis of two climatic features like hot and cold. Types are continental cold (CTc), continental hot (CTh), maritime cold (MTc) and maritime hot (MTh) air mass.
