My research interests have changed over time.  I have investigated the effect of predicted climate change on (future) local weather (using “dynamical downscaling”), the effect of climate change on the intensity of tropical storms, the impact of air pollution (and dust) on tropical and severe storms, and initial conditions and grid-spacing on winterstorm prediction. More recently, my emphasis has turned from research to applications of research ideas.  My emphasis is on using numerical models to improve weather forecasts for the purpose of saving lives and reducing risk to infrastructure.  This involves using high-resolution data sets (such as lightning data) to improve forecasts that can offer advanced warning beyond what is seen by radar or satellite.  In addition, we operated the first fully coupled wildfire atmospheric model (“WRF-SFIRE), which was designed to more accurately forecast wildfire movement and wildfire line intensity. Moreover, because the wildfire model is coupled with the atmospheric model, WRF-SFIRE can predict changes in wildfire intensity (“blowup” or “firestorms”) occurring because of the interaction between the heat of the fire line and the circulation along it.
