Weather conditions at middle latitudes are characterized by complex interactions between air masses, fronts, cyclones, and anticyclones. These interactions are governed by a set of elegant mathematical equations that describe the behavior of the atmosphere. Students will manipulate and apply these equations in real time in order to diagnose the development and evolution of a variety of synoptic-scale weather systems, including fronts, jet streams, and extratropical cyclones. Recommended prerequisite: ATOC 3050, ATOC 4720, one year of Calculus, and one semester of Physics with Calculus. Previously offered as a special topics course. Same as ATOC 4890.
