Here is my weekly weather quiz question for the last time. What is a “temperature inversion?”  Here is the correct answer. A Temperature Inversion (surface-based or elevated) : a layer of the atmosphere in which air temperature increases with height. When the layer’s base is at the surface, the layer is called a surface-based temperature inversion; when the base of the layer is above the surface, the layer is called an elevated temperature inversion. 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.

An upper level low pressure trough that has been controlling our weather is moving to the south away from us.
