Our research group was established at NC State in 2005, and is under the direction of Dr. Matthew Parker.



   


Welcome! Our current research focuses on the dynamics of convective storms, including tornadic supercells and mesoscale convective systems (MCSs). Such storms and systems have great impact upon our society owing to the hazardous weather they produce, and owing to their copious precipitation (which is critical to the water budget in large parts of the Americas). Some meteorological topics of ongoing interest to our group include: impacts of low-level wind and thermodynamic profiles upon supercells and tornadogenesis; storms' sensitivities and interactions in the high-shear regime that spans the MCS-supercellular spectrum; low-level kinematics and dynamics of elevated convection; and, climatology and dynamics of convective storms in the eastern U.S., especially those that occur in environments with low instability.

To pursue these research goals, we utilize idealized numerical simulations (with the benefit of NCSU's supercomputer facilities), conventional observations (e.g. from the National Weather Service), and data from field projects such as the Verification of the Origin of Rotation in Tornadoes Experiment 2 ("VORTEX2"), the Plains Elevated Convection at Night ("PECAN") project, and VORTEX-Southeast.

NC State is a great place to study Mesoscale Meteorology, and North Carolina's Research Triangle is a great place to live! Interested in joining us? Contact Dr. Parker for more information.
