Meteorology 503
Fall 2004
Lab 5
Homework 9
Paper Calcuations
1. All labs are to be kept in a three hole binder. Turn in the binder when you have finished the Lab.
2. Show all work in mathematical problems. No credit given if only
answer is provided.
Report
I. You will present the results of the study in the form of a
report. The report will have
a standard format styled on American
Meteorological Society Format guidelines.
(Metr 403)(Introduction, Synoptic Overview, Equations, Appendices,
Maps, References). First try at set of analyses and
computations.
(Metr 503) Revision and
completion. Includes posting to
web and PowerPoint Presentation to class.
Consists of ÒhistoryÓ of paired surface and upper air system. Studentanalyzed surface charts, 500 and 300 mb charts for 00 UTC, 12 UTC, 00 UTC (22 October 2004) and 12 UTC (23 October 2004).
fax ua_300, 500, 700 and 850 printouts for the same times. Also, includes satellite and radar imagery as needed. A Òsynoptic overview or historyÓ is basically a complete weather briefing of what happened to and associated with the weather system in question.
Specialized Charts for Analyses
1000500 mb thickness, 500 mb heights/vorticity (use thickness and voricity plotted and contoured by eta_maps –times init either eta_thick or eta_vort for the three times), 1000 mb heights for the same times.
1. Examine the detailed procedure sheet for Map Times 1 through 3. For the boxes labeled A, B, C, D, I, J, K, L, Q, R, S and T indicate what charts or data you would need to obtain. Also, in one sentence indicate a general procedure to obtain the required field.
2. (Homework 9) Print out the 1000 mb height chart (3
dm interval) for each synoptic time.
Use the contiguous US map background that is default for wxp. Now, calculate the absolute geostrophic
vorticity at 1000 mb using the same finite difference cross you utilized in
Labs 3 and 4. Make sure you add
the correct value of Coriolis parameter to get the absolute vorticity (and when
multiplying by g/f to get the relative vorticity).
Diagnosis of the Evolution
of a Middle Latitude Cyclone
on the Basis of
SutcliffePetterssen Development Equation
Abstract
I. Introduction  (Includes purpose and what you
are going to do, etc.)
II. Synoptic
Overview (A discussion of the synoptic situation and history of the
disturbance utilizing appropriate charts and diagrams; e.g., upper troposphere, surface
charts, divergence, vertical velocity fields, satellite imagery, thickness
etc. Can consist of multiple
subsections related to dynamics and thermodynamics. In certain case studies, another section related to
subsynoptics may be appropriate.)
III. Governing Equations (Not the whole derivation, which
should be in the Appendices, but the final equation with all the terms written
out and conceptually explained. For example, in section II you might put
something like "The SutcliffePetterssen Development Equation is
(1a,b)
The entire derivation of this equation is included in
Appendix 1.").
IV. Procedure (Write in your own words what procedure was undertaken to
estimate terms etc. which times were selected etc.).
V. Results of the study (A detailed description of your
numerical results and their implications)
VI. Discussion of results  Should
include, but not necessarily limited to:
a. a
discussion of the contributing factors to the development of the 1000
mb
disturbance or pattern based upon your calculations as input to the
SPDE introduced in II. This
discussion should include the relative
importance of terms, the reasons for error, etc.
b. a
discussion of the worth of the SPDE equation as a synopticians tool
synopticians often only relate cyclonic vorticity advection at LND
(anticylonic vorticity advection at LND) to surface cyclogenesis (anti
cyclogenesis). Based upon
the results of your study, comment on the
validity of that assumption.
VI. Summary and Conclusions
V. Appendices
Equations etc. (any derivations that are extensive and not specifically related to the
main thrust of the paper.)
VI. Maps  (all analyses should be labeled
consecutively Figure 1, Figure 2, etc. and referred to specifically in the
text. They will be folded neatly
and put into envelope at rear of folder)
