Paper on updrafts in hurricanes and how they relate to intensity changes published in Monthly Weather Review
Summary: NOAA Hurricane Hunter aircraft have a Doppler radar that measures wind through the entire hurricane. We analyzed these radar data collected in many hurricanes since 2004. Previous studies found that the location of the fastest upward moving air (what we call updrafts) may tell us how strong the storm will be a few hours …
Best Student Poster at AMS 33rd Hurricane Conference
The Best Student Poster for Mesoscale Meteorology Award at the AMS 33rd Hurricane and Tropical Meteorology Conference was awarded to University of Utah student George (Trey) Alvey III and co-authored by HRD's Rob Rogers and Jon Zawislak along with U. Utah Professor Ed Zipser. The poster was titled "Hurricane Edouard's (2014) Intensification: The Relationship between …

Paper on the difference between rapidly intensifying storms and those that don’t intensify as fast published in Journal of the Atmospheric Sciences
Summary: The main model that forecasters use to predict what a hurricane will do is the Hurricane Weather Research and Forecast (HWRF) model. Because we cannot measure what is currently happening in the hurricane exactly, we run the model many times at once with different measurements to get an idea of the different forecasts that …
