Summary module description:
Dynamical knowledge of the development of synoptic-scale weather systems
in the extra-tropical latitudes will be developed in this module.

Aims:
To develop a modern understanding (from the 'potential vorticity
thinking' perspective) of the dynamics of synoptic-scale weather systems
in the extra-tropical latitudes, and to relate this knowledge to
observations.

Assessable learning outcomes:

By the end of this module the student should be able to:



• Provide a suitable mathematical and conceptual description of mid-latitude, synoptic-scale weather systems;



• Explain, physically and mathematically, the origins of synoptic-scale vertical motion, waves and cyclones, and develop quantitative estimates of their properties;



• Critically assess the relevance of conceptual models through comparison with observations.


Additional outcomes:
Students will enhance their skills in the quantitative analysis of
weather systems and the
scaling of atmospheric motions. Students will learn to validate their
calculations through physical principles.

Outline content:

• Equations for the extra-tropics;



• The quasi-geostrophic equations;



• Potential vorticity thinking;



• Vertical motion and the omega equation;



• Dynamical interpretation of regions of vertical motion in cyclones and fronts;



• Rossby waves;



• Conceptual models of baroclinic and barotropic instability;



• The Eady and Charney analytical models of baroclinic instability;



• Lifecycle of cyclones;



• Scaling of fronts and the semigeostrophic and Sawyer-Eliassen equations;



• Symmetric and convective instability.


Brief description of teaching and learning methods:

Lectures and (un-assessed) problem sheets. Students will give an oral and/or poster presentation on an agreed topic based on a published paper (assessed, 25% of the final mark). Full course notes and model answers to the problem sheets are provided.
