Roll Clouds
Roll clouds are just one of the weird weather phenomenon that can happen when winds go wild. Roll clouds are a type of arcus cloud, which is a category of low cloud formations. They sometimes form along with storms too, born out of the storm’s downdraft. Sinking cold air causes warm, moist air on the planet’s surface to climb to higher altitudes, where the moisture condenses into cloud form.
