This Webcast features Phil Schumacher, NWS Sioux Falls, South Dakota discussing the conditions that dictate the location of precipitation relative to inverted troughs. Phil presents a composite case study based on collaborative research with Dr. R. Weisman and others, as well as two examples of inverted trough events in the Central Plains. This presentation is based on his presentation at the MSC Winter Weather Course, December 2002, in Boulder, Colorado. The webcast is accompanied by a case exercise, Inverted Trough Case Exercise.
1. Describe inverted troughs and their associated precipitating features.
2. Present the results of a composite inverted trough study, based on the differences between inverted troughs that produce precipitation ahead vs. behind the trough.
3. Demonstrate the use of isentropic techniques in diagnosing important inverted trough features.
4. Look at several case studies demonstrating the impact of inverted troughs on precipitation distributions.
