NCSA and the Department of Climate, Meteorology & Atmospheric Sciences (CliMAS) will host Paul Markowski, a distinguished professor of meteorology and head of Penn State's department of meteorology and atmospheric science, on Tuesday, March 24, at 3:30 p.m. CT as part of the NCSA Colloquium Series.
The talk will take place in the NCSA auditorium and virtually.
Abstract
A simulation of a supercell storm produced for a prior study on tornado predictability is reanalyzed for the purpose of examining the fine-scale details of tornadogenesis. It is found that the formation of a tornado-like vortex in the simulation differs from how such vortices have been understood to form in previous numerical simulations. In this talk, we will look at the differences between the present simulation’s inclusion of a turbulent boundary layer in the storm’s environment and past simulations’ use of a laminar boundary layer. Time-permitting, we will share some musings on non-equilibrium lower boundary conditions and their potential impact on supercells and tornadoes.
