An air mass abbreviated cp has what temperature and moisture characteristics?

Air mass abbreviated Cp has cold temperature and dry moisture.

Explanation:

Air mass abbreviated Cp means regions of continental polar or continental arctic. So mostly in the northern hemisphere where the temperature is very low like in Alaska, the mass of air is termed as Cp. At those low temperature, the temperature is very cold and so the moisture present in the air in those regions will be dry in nature. Mostly, they originate in the northern hemisphere like in canada, Alaska and then they will spread toward the south and east directions.

So they air masses present in those cooler regions are extremely cold and has dry moisture.
