About
I am the federal lead for PSD's
"Attribution and Predictability Assessments" team. Additionally, I
perform, coordinate, and lead R&D to improve NOAA's
probabilistic weather forecasts on time scales of days to several
weeks. The probabilistic forecasts are based on ensembles of
weather simulations using different initial conditions and methods
for simulating imperfections in the forecast model. I also am
involved in the "post-processing" of ensembles of forecasts,
making corrections to the real-time forecasts based on
discrepancies noted between past forecasts and observations or
analyses. My team and I develop these research methods,
demonstrate their suitability for operational use, and then work
with colleagues in the National Weather Service to adapt them for
daily use by forecasters and the public. We document our work in
the form of peer-reviewed journal articles, presentations, white
papers, book chapters, and so forth.
