Reviews the basic equations that are used to describe the physical state of the atmosphere.
Gives an overview of conceptual models of the structure of the atmosphere and associated “weather systems”, such as cloud and precipitation systems, jets, the polar vortex, the tropical Hadley circulation, mid-latitude cyclones and associated thermal fronts.
Introduces theoretical concepts such potential temperature, potential vorticity, thermal wind balance, hydrostatic-, inertial- and baroclinic- instability, equivalent potential temperature, frontogenesis and potential vorticity inversion.
Discusses waves, from sound waves to Rossby waves, and wave propagation in the atmosphere.
Uses the quasi-geostrophic approximation to present a theory of the formation of mid-latitude cyclones
Introduces the Q-vector and the omega-equation to give insight into the formation of large scale layered cloud and precipitation systems and to interpret the life-cycle of mid-latitude cyclones
The student is required to do a case studying in which she/he formulates a hypotheses, collects appropriate data, analyses this data in order to test his/her hypothesis, and presents the results of this study in an oral presentation and a written report
Introduction into the theory of motions associated with weather systems in the atmosphere. The principal processes that will be discussed are wave motions associated with compressibility, gravity and rotation, motions associated with adjustment to hydrostatic, geostrophic and thermal wind balance and motions associated with hydrodynamic instability. Potential vorticity and frontogenesis are central concepts. Examples of weather systems that will be discussed are seabreeze circulations, thunderstorms, fronts and cyclones.

BeoordelingThe assessment is based on one mid-term exam (retake in December), one modelling project, one data-analysis project and two hand-in exercises.
The results of the modelling project should be presented in the form of a written report. The results of the data-analysis project should be presented orally at the end of the course. Both these projects are done in couples.
