Advanced dynamical meteorology

Dynamical meteorology concerns itself with the causes of atmospheric motion. The unit begins with a scale analysis of the equations of motion for mid latitude weather systems, which leads to the most important theoretical development modern meteorology - the quasi-geostrophic theory. This theory and its generalisation, is used to explain Rossby waves and their interaction with the mean state, the development of extratropical cyclones, the causes of vertical motion, and the structure and evolution of cold fronts. The theory for gravity waves is developed also.
