Good afternoon, I am hoping that someone can assist me with understand an assignment that I was given. I am supposed to find a map of the jet stream on any website (the example given was www.accuweather.com/en/us/national/weathersurface-maps) Using the current jet stream information I am supposed to determine where the coldest air is located and why. I attempted to do this yesterday on the site provided but I don't believe that I am understanding the concept very well. I will not post the whole answer I came up with here, but in very basic terms I said the coldest air would be to the west, specifically Idaho, Wyoming, and parts of Colorado because this is the pocket of the deepest "dip" in the stream. I really have no clue if this is even remotely correct and even after reading the assignment and my text book several times I think I am missing something. Can anyone please provide a better understanding of this concept? Thank you in advance for your assistance. P. Beck
