Book chapter on monitoring tropical cyclones with the Synthetic Aperture Radar published

  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 …

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 …

Paper on measurements of extreme wind speeds and updrafts in hurricanes published in Monthly Weather Review

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 …
