Final answer:
Yes, the west coast can occasionally get continental polar air masses due to certain weather patterns such as the Arctic Oscillation and the formation of high-pressure systems inland.
Step-by-step explanation:
Yes, the west coast can occasionally get continental polar air masses. While the west coast of the United States generally experiences a maritime climate influenced by the Pacific Ocean, there are certain weather patterns that can bring continental polar air masses to the region. One example is the phenomenon known as the Arctic Oscillation, which can cause cold air to move southward from regions near the Arctic Circle and reach the west coast. Another example is when a high-pressure system forms inland and pushes cold air towards the coast. These events are relatively rare but can lead to colder temperatures and different weather conditions on the west coast.
