Satellite images taken from an instrument called the Synthetic Aperture Radar (SAR) that can see things on the earth’s surface that are about 100 m (300 ft) across are used study the wind in tropical cyclones. The SAR can see small swirls (called vortices) near the eye of the hurricane, small long, thin lines […]
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 […]

Dropsondes are instruments released from Hurricane Hunter aircraft that measure temperature, humidity, and wind speed as they fall to the ocean. Since they were first used in 1997, more than 12,000 have been dropped into tropical cyclones (hurricanes and typhoons) around the world. All of these observations are studied to find those with the fastest […]
On Tuesday, May 19, 2015, Dr. Robert Rogers led a kick off meeting to discuss our flight experiments and modules that will be part of the 2015 hurricane field campaign. Click here to review the proposed experiments.
Sixteen HRD scientists participated in the recent 31st AMS Conference on Hurricanes and Tropical Meteorology, being authors or co-authors on 34 presentations and 9 posters. Roughly 750 presentations (442 oral presentations in 70 sessions and 308 posters in 2 session) were submitted to the conference. Of the 496 TC-related presentations and posters at the conference, 130, or about 26%, […]
Abstracts and recordings of the 6 presentations and 5 posters AOML & HRD researchers presented (or were co-authors) at the 94th AMS Annual Meeting are available online from the AMS website: Presentations: Status on reaching the Goals of the Hurricane Forecast Improvement Project (HFIP) Robert L. Gall, NOAA/NWS, Silver Spring, MD; and F. Toepfer, F. Marks, […]
Congratulations to Sarah Ditchek of Yale University, a 2012 NOAA Hollings Undergraduate Scholar, who presented her work, “Eyewall Mesovortices in Hurricane Fabian (2003) using the HWRF Ensemble Data Assimilation System (HEDAS)”, at the 2013 NOAA Science and Education Symposium. Sarah spent 8 weeks at HRD during the summer. Sarah also gave an oral presentation of […]
