EAS 471 Atmospheric Modelling
January-April, 2014
Announcements
- Final exam (with answers).
- Final exam will consist of: 18 multi-choice questions (value: 9%); three "paragraph answer" questions (value: 3x2%); and three "long answer" questions (3x5%) chosen from five offered. Emphasis will be topics covered after the midterm exam, and (of course) there will be no questions on topics not covered this year (such as radiation modelling). Pertinent equations will be given as data. Excluded: material concerning 3D-bLS (part of the final lecture).
- Instructor's solutions for lab 2: (a) using Matlab, a 3D view and a slice through y=0; and (b) using Fortran 90, slices at y=0 and y=1/8 (plotted using the free software Veusz). As the number of terms included in the analytical solution increaes to infinity, ever shorter waves (higher wavenumbers) contribute and the analytic solution captures the "peakiness" of the delta function. In the numeric solution, the equivalent progression towards the true solution is made by refining the resolution (reducing the gridlength Δ), so that the heat source, ideally a delta function (if seen in cross section through y=0, is represented by an increasingly narrow (but higher) triangle (always preserving unit area).
- Third (and final) scored lab: Lagrangian stochastic simulation of Project Prairie Grass surface layer dispersion trials. Due: Tuesday 8 April. (File corrected 18 Mar.)
- The final exam is scheduled for 09:00-11:30 on Tuesday April 15th in ESB 1-39. Note: the UA timetabling system is incapable of admitting anything but an integer for exam duration, however as announced on the course outline, 2.5 hrs will be allowed.
- Draft plan for topics covered and order of doing so. Please take your own notes. There will be no handout, but references will be made to available material in case you wish to explore more widely: for instance Wikipedia articles, or journal articles placed on our web site. Pace of lectures can be adjusted according to need: by all means, slow me down by asking questions so that you can keep up. If possible, review lecture material soon after class and bring up any questions in the following class.
