Here is my weekly weather quiz question for the last time. What are “Gyres?” Here is the correct answer. Gyres are oceanic current systems of planetary scale driven by the global wind system. 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.
