Answer to Question 1

Answer: continental polar

Answer to Question 2

Answer: Maritime polar air forms over the North Pacific as cP air moves out from the interior of Asia. The warm Japan current adds heat and moisture to the cold, dry air and converts it from cP to mP. The developing air masses migrate eastward across the Pacific; most of them pass across the Gulf of Alaska before reaching the west coast of North America. They approach the northern west coast of North America throughout the year but influence the California coast mainly in the winter.
