Drs. Simon and Penny presented a seminar on “An evaluation of the HFIP Corrected Consensus Approach (HCCA) for tropical cyclone track and intensity forecasts”. Abstract: Prior to the 2015 hurricane season, the Hurricane Forecast Improvement Project (HFIP) Corrected Consensus Approach (HCCA) was implemented at the National Hurricane Center (NHC) as an “in-house” guidance product for […]
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 […]
Summary: Observing tropical cyclones around the world can be very expensive because they occur over oceans where there are few observations. Hurricane Hunter aircraft can reach hurricanes only when they are close to land. Thunderstorms near the centers of tropical cyclones cause waves (called “gravity waves”) in the atmosphere that move outward in spiral […]
African easterly waves (AEWs) are areas of low air pressure that move westward across North Africa and into the Atlantic Ocean. AEWs can cause intense thunderstorms, and, once over the warm waters of the Atlantic Ocean, they may become tropical cyclones that might affect the Caribbean and North America. In summer, many AEWs form in, […]
Starting in 2010, the National Aeronautic and Space Administration and the National Oceanic and Atmospheric Administration have used the Global Hawk, an unmanned aircraft that can fly at 65,000 feet for 24 hours at a time, to make observations in tropical cyclones. The Global Hawk can release dropsondes that measure temperature, humidity, pressure, and wind […]
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 […]

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 […]
