Paper on how the region near the ocean surface impacts hurricane forecasts released online in Monthly Weather Review
Summary: Forecasters and researchers use the Hurricane Weather Research and Forecasting (HWRF) model to forecast where a hurricane will go, how strong it will be, how large it will be, and where the strongest winds are. This paper looks … Continue reading

Two-part paper on the intensification of Hurricane Edouard published in Monthly Weather Review
Summary: Hurricane Edouard (2014) is examined using radar onboard NOAA P-3 aircraft that flew the storm. Two periods are shown, one when the storm was intensifying to a major hurricane and the other when the storm was weakening. The location … Continue reading
