Listed below are the major concepts that you should know when finished with this unit

Objective 1: Identify the three convective variables necessary for thunderstorms, and discuss the role they play in thunderstorm development.

Objective 2: Identify the three basic stages in the thunderstorm lifecycle and the accompanying storm structure using schematic diagrams and actual images, and describe the major processes occurring within each stage. (key terms include inflow/updraft; outflow/downdraft; gustfront; flanking line; backsheared anvil; rain-free base)

Objective 3: Explain the steps involved in the formation of lightning, including the pools of separate charges in the cloud and at ground level, the role of the stepped leader, creation of positive streamers, and the resulting return stroke.

Objective 4: Describe the process of hail formation, its location within the thunderstorm, and why that location is so important.

Objective 5: Identify the factors involved in producing flash-flooding events, and why they are so dangerous. Include information regarding the dangers of flash-flooding with regard to automobiles.

Objective 6: Classify downbursts as macro or micro, and within microbursts identify each as wet or dry. Describe the stages in downburst formation, and compare/contrast downburst damage patterns with tornadic damage patterns.
