SAN FRANCISCO STATE UNIVERSITY		METEOROLOGY 403
DEPARTMENT OF GEOSCIENCES		Fall 2004
	Homework No. 7

This homework assignment involves use of the data that you have archived for the term paper.

1. Print out the following:

a. Plot of the surface hourlies for 0000 UTC 22 October 2004 (you can use the "wxp" training wheels menu, and just choose "Plotting Programs", then "Plot Surface Data" with the map background "Contiguous US";

b. Next, use the script "fax" to obtain the 850 mb, 700 mb, 500 mb, 300 mb charts;

c. Next, use the script "eta_maps" to obtain the initializations for "eta_thick" and "eta_vort".

2. Perform a temperature advection analysis on the Sfc/1000-500 mb thickness initialization, and draw in your estimates for fronts based upon this chart alone.

3. Indicate areas of significant vorticity advection (cyclonic– green shading;

anticyclonic– brown shading) on the 500 mb/Ab vorticity initialization.

4. Indicate trough and ridge axes on the 700 mb, 500 mb, 300 mb. (Don't ask! See M301 website for correct symbols).

5. Analyze the surface chart synoptically. Please don't ask what that means. If
