This article will be a simpler one than the previous weeks, but something that I bet all of you have been wondering; Where do cold fronts come from? As I informed y’all in a previous article the movement of fronts is just the way the atmosphere tries to equalize pressure in the atmosphere. There cannot be a cold front without there also being a warm front in the area. As of the publishing of this article, we are in a warm front, even if it does not feel so warm, so that the cold front on Wednesday night can give us some cooler weather. This upcoming cold front is coming from northwest Canada and is being moved down here by the upper air movement of the jet stream. The jet stream is high in the upper atmosphere around 6-12 miles above the ground that moves at speeds of 150 mph. The Jet Stream moves the lower atmosphere the same way that if you run your hand through tall grass. If you hit the top of the grass the top moves drastically, but as you go farther and farther down the blade of grass right near the bottom it barely moves compared to the top of the blade of grass. This is a good example as the grass is connected from top to bottom as one blade of grass and the atmosphere is connected by the friction between the air molecules. So the upper atmosphere is moving very fast but at the ground it’s just a fraction of the speed of the upper atmosphere.
