On 14 July, 1997, Tropical Storm Claudette was moving northeastward offshore the east coast of the US. Eager to test the new Gulfstream-IV (G-IV) jet aircraft and the new Global Positioning System dropwindsonde, the National Hurricane Center tasked the first-ever operational synoptic surveillance mission geared toward improving track forecasts. Initial condition differences in the […]
Summary: Hurricane Hunter aircraft have been releasing instruments called dropwindsondes to measure pressure, temperature, moisture, and wind speed and direction in hurricanes for two decades. Data from dropwindsondes released near the storms have led to better forecasts of where they will go, but improvements to forecasts of how strong they will get have lagged. Part […]
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 […]
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 and AOML scientists participated in the 71st Interdepartmental Hurricane Conference/Tropical Cyclone Operations and Research Forum. HRD scientists presented or were coauthors on 14 of the 45 presentations and 3 of the 10 posters. Shirley Murillo chaired the Joint Hurricane Testbed (JHT) session and Sundararaman Gopalakrishnan chaired a panel discussion on “Research Supporting Operations: Current […]

In October 2015, off the west coast of Mexico, Hurricane Patricia became the strongest hurricane ever recorded in the western hemisphere, intensifying faster than any other storm on record. A unique set of observations were collected in Patricia. National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration/Office of Naval Research (ONR) aircraft […]
Dr. Aberson presented a seminar titled “Dropsondes in Hurricanes (1949 to the present)” Abstract: The history of the use of dropsondes in hurricanes will be presented with special emphasis on the achievements since the development and implementation of the NCAR GPS dropwindsonde 20 years ago. The GPS dropwindsonde revolutionized the science of hurricanes. Though originally developed […]
November’s science meeting consisted of 7 presentations: Shun-Nan Wu (RSMAS), “The signal of future TC intensification in the CloudSat measurements” Jon Zawislak (FIU/CIMAS/HRD), “The Relationship Between Precipitation and Environmental Forcing during Tropical Cyclone Formation” Leon Nguyen (HRD), “Thermodynamic and kinematic influences on precipitation symmetry in sheared tropical cyclones: Bertha and Cristobal (2014)” Brad Klotz (CIMAS/HRD): […]
