Research Interests:
Severe convective storms
and their interaction with mesoscale features in their environments, tornadogenesis,
radar observations of tornadic thunderstorms, convective initiation, and
numerical modeling.
Dr. Richardson's research focuses on understanding the formation and
evolution of severe storms through both numerical modeling and observations.
In particular, her numerical modeling studies investigate the influence
of temporal and spatial variations in environmental shear and/or convective
available potential energy on storm strength, rotational properties, and
longevity. Her observational work has focused on understanding storm rotation,
in particular tornadogenesis, using mobile radars to collect fine-scale
observations of thunderstorms and tornadoes. Dr. Richardson was also a
principal investigator in the International H20 Project (IHOP) in Spring,
2002 with a focus on convection initiation and boundary layer processes
using mobile radar data combined with other remote and in-situ measurements.
Teaching Interests:
Atmospheric
dynamics, mesoscale processes in the atmosphere, atmospheric convection,
thermodynamics, radar meteorology, survey of atmospheric science.
