Two part paper on convective bursts in hurricanes published in Monthly Weather Review

These two papers analyze extreme upward air currents, called “convective bursts,” in hurricanes that have been believed to be important for hurricane intensification. We use the Weather Research and Forecasting (WRF) model to look at convective bursts in two hurricanes: Hurricane Dean from 2007 and Hurricane Bill from 2009. In the first paper, we study […]

Paper on the bumpy ride encountered by Hurricane Hunters in Hurricane Felix published in Monthly Weather Review

On September 2, 2007, a National Oceanic and Atmospheric Administration Hurricane Hunter airplane flew into Hurricane Felix when it was a category-5 hurricane north of Venezuela. The aircraft measured wind speed of 163 kt (188 mph) at the ocean surface and an upward wind speed of 60 kt (69 mph), the fastest upward wind ever […]

HRD Seminar – Dr. Jason Dunion, CIMAS and AOML/HRD – 4 May 2017

Dr. Dunion presented a seminar titled  “The Tropical Cyclone Diurnal Cycle: The Great Hurricane Exhale”. Abstract: New geostationary infrared satellite imagery has revealed a curious diurnal pulsing pattern in tropical cyclones (TCs) that may represent an unrealized, yet fundamental process of mature TCs.  These diurnal pulses begin forming in the storm’s inner core near the time […]

Paper on a new dropwindsonde that measures sea surface temperature released online in the Journal of Atmospheric and Oceanic Technology

Warm water provides the energy for tropical cyclones to form and intensify, and knowing the temperature of the water is important in predicting how strong a hurricane will become. Dropwindsondes are instruments that measure air temperature, moisture, pressure, and wind velocity as they fall toward the ocean after release from Hurricane Hunter aircraft, but they […]
