Summary module description:
Dynamical knowledge of the development of synoptic-scale weather systems
in the extra-tropical latitudes will be developed in this module.
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
Assessable learning outcomes:
By the end of this module the student should be able to:
mid-latitude, synoptic scale weather systems.
- Provide a suitable mathematical and conceptual description of
vertical motion, waves and cyclones, and develop quantitative estimates
- Explain, physically and mathematically, the origins of synoptic-scale
of their properties.
- Critically assess the relevance of conceptual models through
comparison with observations
Students will enhance their skills in the quantitative analysis of
weather systems, the manipulation of differential equations and the
scaling of atmospheric motions. Students will learn to validate their
calculations through physical principles.
- 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
- 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 a brief
presentation on an agreed topic (assessed, 25% of the final mark). Full
course notes and model answers to the problem sheets are provided.
Students will be invited to read through selected chapters of one or

Formative assessment methods:
Un-assessed problem sheets will be completed by the students and the
answers discussed during lectures. Model answers will be provided for
these problem sheets.
