This Webcast is a recreation of a presentation on slantwise convection given by Kent Johnson in February, 2002 in Boulder, Colorado. It focuses on assessing the release of conditional symmetric instability as slantwise convection. It provides an overview of the characteristics and theory of CSI, assessment of CSI and slantwise induced precipitation in complex terrain, and operational challenges to assessing CSI.
1. Show that the atmosphere can be intertially and gravitationally stable, but unstable to a slantwise displacement when near or at saturation.
2. Demonstrate the vertical-cross section approach in diagnosing the potential for conditional symmetric instability (CSI).
3. Examine ways to improve forecasts that involve a potential slantwise convection situation.
4. Examine the typical characteristics of CSI in complex terrain.
5. Apply a slantwise convection analysis to a real world situation.
