# General information

Students will be introduced to the formal mathematical characterization of atmospheric motions, to forces acting in the atmosphere, and to equations of atmospheric kinematics and dynamics. Particular topics include coordinate systems used in meteorology, basics of vector calculus, Newton’s laws of motion, conservation of mass and energy, basic force balances and atmospheric motion types, concepts of equilibrium and stability in the atmospheric context, and equations of motion.
