Here is my weekly weather quiz question for the last time. Define “sastrugi.”  Here is the correct answer. Sastrugi are ridges of snow formed on a snow field by the action of the wind. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.
