Study on how Hurricane Dorian organized before rapidly intensifying published in Monthly Weather Review
This study showed that a weak, disorganized tropical system in an environment that is not primed for intensification can develop a new center where conditions are more favorable for intensification. The ability to observe the center of circulation, the tilt of the vortex with height, the depth of the vortex, the wind shear, and locations […]

Paper describing a new forecast model that follows multiple tropical cyclones at the same time published in The Bulletin of the American Meteorological Society
Forecast models that follow individual tropical cyclones (TCs), like NOAA’s Hurricane Weather Research and Forecasting (HWRF) model, have contributed to significant improvement of intensity forecasts for over a decade. The original HWRF could only follow one TC, but recent advances allow individual multiple nests to follow more than one TC. This is the first time […]
