Research Interests

As a branch chief in the NOAA/ESRL Global Systems Division, I lead a group that focuses on developing the next-generation weather models, data assimilation techniques and other research projects aimed at improving operational weather up to seasonal forecasting. We contribute to regional and global model development, and we collaborate extensively with NOAA’s National Centers for Environmental Prediction (NCEP), the National Center for Atmospheric Research, other groups in NOAA/ESRL and other laboratories and universities.


Current Research

Some of my branch’s current projects include:

  • Development of Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR), two experimental models developed in the Global Systems Division which are now operational, helping weather forecasters around the country predict rapidly changing weather conditions including tornadoes, flash flooding and severe snowstorms.
  • Development of the Flow-following finite-volume Icosahedral Model (FIM). This still-experimental global model uses an icosahedral grid, one composed of evenly sized pentagons and hexagons rather than a more conventional grid based on latitude and longitude. FIM’s other features—an adaptive vertical coordinate system that concentrates around frontal zones and the tropopause) and finite-volume horizontal transport— improve global forecast skill.
  • Work with several models to improve hurricane forecast guidance. For example, we provided experimental forecast guidance to the NOAA National Hurricane Center during the 2014 season, through the NOAA Hurricane Improvement Project.
  • Directing application of HRRR and RAP for the aviation/transportation community and for renewable energy, including ongoing wind and solar energy projects for the Department of Energy and NOAA, to improve energy management toward more efficient use of renewable energy.
