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 […]
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 […]

The purpose of the observation team meetings is to bring together the people who use observations in their research on a regular basis to discuss issues they’re having, provide updates on observations they’re analyzing or collecting, and any other information that may be of interest to the broader group. These meetings are also an excellent […]
March’s science meeting consisted of 4 presentations: Thiago Quirino: Next-generation, Multi-Scale Tropical Prediction System: Transitioning HWRF to the NEMS Framework under NOAA HIWPP Xuejin Zhang: Basin-scale HWRF Verification Sim Aberson: Hurricane Felix 070902H Robert Rogers: Role of deep vs. shallow convection in RI onset All the presentations and posters are available on the anonymous ftp […]
July’s Science meeting had 4 presentations: Kelly M. Núñez Ocasio: An Extreme Event in the Eyewall of Hurricane Felix Robert Nystrom: Storm-Relative Correlation Structures Joseph Patton: Extratropical Transition of Hurricane Sandy Robert Rogers: Deep convection and its role in RI The presentations are available on the anonymous ftp site at: ftp://ftp.aoml.noaa.gov/hrd/pub/blog/meetings/2014/science/HRD_SciMeet_20140710.zip
HRD is hosting four students this summer as part of various NOAA programs and collaborations with research partners. Robert Nystrom is a NOAA Hollings Scholar from the University of Illinois at Urbana-Champaign. He is working with Altug Aksoy to investigate storm-relative correlation structures in ensembles of idealized hurricane simulations. Joseph Patton is also a NOAA Hollings Scholar, and […]
