Welcome! Our current research focuses on the
dynamics of mesoscale convective systems (MCSs) and other severe
convective storms. MCSs are common throughout the Americas, and they
account for both a large fraction of the growing-season precipitation in
the central Plains and a disproportionate number of the flash floods that
affect our society. We are investigating non-traditional MCS archetypes
with the aim of improving our understanding of and ability to predict
various recurring MCS modes. For example, we have learned about convective
lines with leading and parallel precipitation by combining observations and idealized
modeling. Our current efforts at NCSU include studies of particularly
well-observed non-traditional MCSs from the BAMEX field program and of
severe wind-producing MCSs, as well as numerical experiments studying convection in increasingly "life-like" environments: elevated storms, storms along fronts, and storms that evolve differently in seemingly similar environments.
Related topics of interest include the effects of gravity waves on the environments of convective systems, and the impacts of interesting wind and thermodynamic profiles upon supercells and tornadogenesis.
We are also continuing to work on the statistical properties of convection and convective initiation, including cell identification and tracking, eastern U.S. modes of variability, and convective initiation along the eastern sea breeze front.
We have also recently investigated the possible effects of swaths of crop damage upon subsequent
convective initiation and maintenance. Finally, we are now beginning a pilot study of tornadoes in landfalling tropical cyclones.
To pursue these research goals, we utilize idealized
numerical simulations (with the benefit of NCSU's supercomputer facilities)
as well as observations from the National Weather Service (e.g. Doppler
radar data) and field projects (e.g. BAMEX).
