5th edition Essentials of Meteorology: An Invitation to the Atmosphere by C. Donald Ahrens. Bought to accompany an Introduction to Atmospheric Science course. I purchased it used, there is minimal highlighting in the first chapter only. It is still in great shape and is a great book for anyone interested in meteorology. I am not a science major but took the course because I am a novice storm chaser and it was very informative. If you have questions please email or text 608*728*3075. Shipping cost would be extra.
