A suite of 52 idealized
WRF simulations were carried out to investigate how the presence of nearby
cells modified long-term storm behavior.
Analysis of model results included standard metrics (e.g. updraft
intensity), thermodynamic and microphysical properties (e.g. cold pool area and
magnitude) and rotational measures (surface vorticity features were
automatically tracked to diagnose rotation longevity, intensity, and
near-mesocyclone thermodynamic environment). Our presentation will discuss
analysis methods as well as our finding of a surprising link between unsteady
downdraft bursts and mesocyclogenesis events.
