What is the characteristic of a Continental Polar (cP) air mass?

• A. Cold and dry
• B. Warm and humid
• C. Cold and humid
• D. Hot and dry

Answer: (A)

A Continental Polar (cP) air mass is characterized by being cold and dry. This type of air mass typically forms over land areas in polar regions, where the influences of land proximity and higher latitudes lead to cooler temperatures and lower humidity. As a result, continental polar air lacks significant moisture, making it generally dry. Unlike air masses that form over oceans, which tend to be warm and humid, or those that come from tropical regions, continental polar air masses remain cold due to their formation in regions where sunlight is limited and the ground has cooled. Because they originate over land rather than water, these air masses do not pick up substantial moisture, resulting in the dry characteristic. The other options describe air masses with different characteristics; for example, warm and humid air masses typically arise from maritime tropical sources, while cold and humid air masses would be found in different polar conditions where moisture is present. Hot and dry air masses do not relate to the characteristics of the continental polar type either, as that would pertain more to continental tropical air masses.
