Homework 4: Due at Beginning of Class, September 30, 2011).
Explain the following from Chapter 2 of Doswell and Bosart:
"...rising motion favors a decrease in static stability below the level of peak ascent, usually somwhere in the mid troposphere....therefore, ETC's should exhibit some asymmetry in their vertical motion patterns beyond that derived from QG theory; ascent should be more intense than descent...."
You need to make an attempt to explain both halves of the statement. Why is the first part true? And, given that, why is the second half true as well. Specifically refer to the QG omega equation in your explanations for a textbook type wave cyclone.
