Recent History:
From August 2012 to June 2016, I was the project manager for NOAA's Warn on Forecast program which researchs NWP methods to predict hazardous weather from convective resolving models. Dr. Pam Heinselman now leads the WoF program for NOAA and NSSL.
Since 2016 I have been the chief scientist for the WoF program where I continue to study storm-scale data assimilation methods, convective predictability, and research new numerical methods to improve non-hydrostatic model predictions.
As part of that work, I am interested in a number of related scientific problems....
Nonhydrostatic atmospheric model development (particularily numerical methods used to solve the non-hydrostatic compressible Reynolds-Averaged Navier-Stokes equations)
The use of the ensemble Kalman filter and the local particle filter to assimilate storm-scale radar and satellite observations for analysis and prediction
Dynamics and predictability of severe storms and tornadoes
Radar and other in situ observations of supercell thunderstorms
I have a broad set of research interests which generally are focused on numerical analysis, simulation, and forecasts of severe convection and tornadoes. My original research interests in supercells and tornadoes can be traced back to nearly my high school days in the late 1970s. While obtaining my undergraduate and Master's degrees at University of Oklahoma in the 1980s, I became an avid storm chaser and eventually was fortunate enough to be able to work on some of the first in situ deployments of instruments near severe storms with my mentors: Howie Bluestein (OU) and later Don Burgess and Bob Davies-Jones (NSSL). I got the modeling bug while doing my work with Dr. Tzvi Gal-Chen on satellite temperature assimilation for my Master's degree. I left Oklahoma in summer of 1986 to begin a Ph.D. at the University of Illinois. I was fortunate to have Dr. Robert Wilhelmson as my dissertation advisor and together we investigated tornadogenesis within supercells using some of the first sub-200m resolution numerical simulations. The work was facilitated and supported by one of the five original and newly formed NSF computing centers, the National Center for Supercomputing Applications. I became very interested in the developing paradigm of "computational science" that is now ubiquitous across most scientific disciplines. During most of the 1990s I was a professor of Atmospheric Sciences at Texas A&M University. In 1999 I was very fortunate to be able to return to my meteorological roots here in Norman as a scientist at the National Severe Storms Lab. My work today continues to focus on severe storms and tornadoes. The tremendous effort and resulting progress by hundreds of scientists during the past 30 years has led to a substantial increase in our scientific understanding of severe weather, and this progress has led to improved forecasts and more accurate warnings for the U.S. public.
