Tornadoes and Supercell Thunderstorms: Applications in Mesoscale
Meteorology
Abstract
The supercell thunderstorm is one of the most powerful, violent, and
destructive forces seen in nature, capable of producing severe flash
flooding, strong surface winds, cloud-to-ground lightning, large hail,
and tornadoes. Most supercell tornadoes occur in the central U.S., but
they can be observed on every continent except Antarctica. However, few
supercells produce tornadoes and predicting tornadogenesis and
subsequent vortex life cycle remains a significant challenge. In this
seminar, we will discuss the environmental setup and basic mesoscale
dynamics that drive supercell formation, structure, evolution, and
tornadogenesis. These dynamics will be put in context with important
observations and concepts that have resulted from field campaigns such
as the Verification of the Origins of Rotation in Tornadoes EXperiment
(VORTEX) and VORTEX2, as well as very high-resolution model simulations.
