A continental polar (cP) air mass is characterized by being cold and dry. When a continental polar air mass moves into an area, the following changes are most likely to occur:
- The temperature will decrease: Since cP air is cold, it will lower the overall temperature in the area it moves into.
- Humidity will decrease: Continental polar air masses are typically dry, so as this air moves in, the humidity will also decrease.
Therefore, the correct statement is:
The temperature will decrease and humidity will decrease.
