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 how small-scale changes in winds in hurricanes impact hurricane forecasts released online in Weather and Forecasting

Summary: Forecasters and researchers use the Hurricane Weather Research and Forecasting (HWRF) model to forecast where a hurricane will go, how strong and large it will be, and where the strongest winds will be. Wind in hurricanes are different over very short distances like 100 m, or the length of a football field, what is …

Paper on updrafts in hurricanes and how they relate to intensity changes released online 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 …

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 …
