Reading 1: The Distinction between Large-scale and Mesoscale Contribution to Severe Convection: A Case Study Example (pdf)
1. Doswell discusses the setting for the Topeka, KS tornado event of May 6, 1983. Despite the fact that the synoptic setting was quite favorable for severe thunderstorm development, Doswell states: "...while the lapse rate field reveals low values of dry static stability in eastern Kansas and southwestern Missouri, there are two major obstacles to convective development in the Topeka area:..." What are these two obstacles?
2. What role does consideration of wind shear have in the problem of forecasting convection?
3. What is Doswell's conception of "large-scale processes"?
4. What is Doswell's definition of a "mesoscale process"?
Reading 2: Doswell, C.A. III, 2001: Severe convective storms -- An overview. Severe Convective Storms, Meteor. Monogr., 28, no. 50, Amer. Meteor. Soc., 1-26. (PDF)
1. According to Doswell, what is the primary observational tool for assessing the large-scale structure of the atmosphre?
2. In the subtropical and polar regions of the planet, synoptic-scale processes are dominated by what, according to Doswell?
3. What observation does Doswell have about changes in the level of accuracy in tornado and severe weather forecasting?
4. What are the three prongs in Doswell's approach to severe weather disaster mitigation?
