Boundary Layer Meteorology

Summary module description:
This module aims to provide the student with an understanding of how small-scale processes affect the thermodynamic and kinematic structures of the atmospheric boundary layer.

Aims:
This module aims to provide the student with an understanding of how small-scale processes affect the thermodynamic and kinematic structures of the atmospheric boundary layer. Practical work aims to illustrate methods of measurement and interpretation of transfer processes within the surface and boundary layer.

Assessable learning outcomes:
By the end of the module, the student should be able to:

Analyse and interpret data retrieved from field observations of turbulent, - radiant and conductive exchange processes.
Describe in physical and mathematical terms some important atmospheric flow phenomena on horizontal scales less than about 10km, and the way in which these are influenced by the Earth's surface and its overlying atmosphere.

Additional outcomes:
The practical (including field) work will enhance team-working skills, and the use of spreadsheet or programs for the analysis of observational data.

Outline content:
The Practical Content covers

Statistical analysis of turbulent wind fluctuations
Latent, sensible heat and carbon dioxide transfer by the eddy-covariance method
Momentum measurements by the profile and eddy covariance method
Estimating surface energy exchanges by the Penman Monteith method

The Lecture Content covers the conceptual and mathematical modelling of:

Surface layer fluxes and their measurement
Evolution of the boundary layer
Turbulence in the boundary layer
Flow over a changing surface
Flow over hills
Flow over vegetation canopies
The urban boundary layer

Brief description of teaching and learning methods:
During term 7 theoretical work will be presented in 16 50-minute lectures. Four tutorial sessions will be used also.
During term 8 practical work takes place. Experimental work is supported by comprehensive notes and lectures, scheduled according to prevailing weather conditions.

Summative Assessment Methods:

Written exam 50%
Report 50%

Other information on summative assessment:
1 short observational report - 10%, 1 long observational report - 20%, 1 presentation plus abstract 5%+5%, 1 advanced assignment 10%

Formative assessment methods:
Four unassessed problem sheets discussed in the tutorial sessions.

Penalties for late submission:
The Module Convener will apply the following penalties for work submitted late, in accordance with the University policy.
where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Length of examination:
2 hours

Requirements for a pass:
