The Arctic air mass is classified as which type?

The Arctic air mass is classified as which type?

• A. Cold air mass
• B. Warm air mass
• C. Moderate air mass
• D. Very cold, very dry, stable air mass

Answer: (A)

Arctic air mass is a cold air mass. Air masses are large bodies of air with relatively uniform properties that form over their source regions. The Arctic region is extremely cold, so the air that forms there has temperatures well below those in mid-latitudes. That makes it a cold air mass by definition. It’s also typically very dry and stable, which is why it’s sometimes described as very cold, very dry, and stable, but the essential classification for this question is that it is a cold air mass.
