AWOC Instructional Component

IC Severe 1: Conceptual Models for Origins and Evolutions of Convective Storms

General Information

Estimated Completion Time

2 hours, 30 minutes

Description

This instructional component describes conceptual models of convective storms. The emphasis is on physical processes associated with these specific storm type hazards: supercell tornadoes, squall line tornadoes, hail storms, multicell storms, and flash flooding.

Prerequisite(s)

None.

Lessons

Lesson 1: Supercell Tornadic Storms
Description	This lesson provides an introduction to the IC and describes all of the objectives. Lesson 1 reviews the factors of shear and buoyancy on supercell storm development. It also reviews recent research on tornadogenesis, including the roles of boundaries and the rear-flank downdraft.
Estimated Completion Time	1 hr

Recommended	See recommended reading list in the Severe Convection PDS, especially PCUs #2 - 4. References for this lesson (PDF): Supercell Tornadic Storms

Lesson 2: Hail Storms
Description	This lesson decribes processes associated with hail, including the role of shear and rotation on updraft strength, buoyancy and steep lapse rates in hail growth zone, effects of melting, growth trajectories, embyro source regions. The lesson also shows favorable hail proximity soundings, and describes characteristics of the hybrid multicell-supercell hailstorm.
