The Role of Surface Drag in Mesocyclone Intensification Leading to Tornadogenesis Within an Idealized Supercell Simulation

open access: yesJournals of the Atmospheric Sciences, 2017
The idealized supercell simulations in a previous study by Roberts et al. are further analyzed to clarify the physical mechanisms leading to differences in mesocyclone intensification between an experiment with surface friction applied to the full wind ...

Mesocyclonic and non-mesocyclonic convective storms in Germany: Storm characteristics and life-cycle

Atmospheric Research, 2021
Abstract A multi-year analysis of mesocyclonic (approximately 4300) and non-mesocyclonic convective storms (more than 100,000) is presented. A comprehensive data set is generated which includes measurements from a lightning location system, a precipitation radar network, as well as information from automated cell detection algorithms based on radar ...

Volcanic mesocyclones

Nature, 2009
A strong volcanic plume consists of a vertical column of hot gases and dust topped with a horizontal 'umbrella'. The column rises, buoyed by entrained and heated ambient air, reaches the neutral-buoyancy level, then spreads radially to form the umbrella.
