Here is my weekly weather quiz question for the last time. What is a “Continental Air Mass?” Here is the correct answer. A Continental Air Mass is a dry air mass originating over a large land area. Contrast with tropical air mass. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.
