Environmental Meteorology Seminar
Per la serie “Environmental Meteorology Seminar” segnaliamo il seminario di David G. Lerach dal titolo “Tornadoes and Supercell Thunderstorms: Applications in Mesoscale Meteorology” organizzato dall’Università di Trento giovedì 7 aprile 2022 alle 14:30. Il seminario, principalmente dedicato agli studenti del corso di Laurea Magistrale in Enviromental Meteorology, si terrà presso presso la Lecture Room 1P – DICAM Via Mesiano, 77 – Trento. Sarà possibile seguire l’evento online via zoom al link https://unitn.zoom.us/j/83219936315Meeting ID: 832 1993 6315Passcode: 279903 Tornadoes and Supercell Thunderstorms: Applications in MesoscaleMeteorology AbstractThe supercell thunderstorm is one of the most powerful, violent, anddestructive forces seen in nature, capable of producing severe flashflooding, strong surface winds, cloud-to-ground lightning, large hail,and tornadoes. Most supercell tornadoes occur in the central U.S., butthey can be observed on every continent except Antarctica. However, fewsupercells produce tornadoes and predicting tornadogenesis andsubsequent vortex life cycle remains a significant challenge. In thisseminar, we will discuss the environmental setup and basic mesoscaledynamics that drive supercell formation, structure, evolution, andtornadogenesis. These dynamics will be put in context with importantobservations and concepts that have resulted from field campaigns suchas the Verification of the Origins of Rotation in Tornadoes EXperiment(VORTEX) and VORTEX2, as well as very high-resolution model simulations.
