Here is my weekly weather quiz question for the last time. What is “Arctic Sea Smoke?” Here is the correct answer. Arctic Sea Smoke is steam fog, but often specifically applied to steam fog rising from small open water within sea ice. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer at the bottom of this page. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs.  Good luck.
