Sundararaman Gopalakrishnan attended the GFDL Hurricane Science Symposium 2 May in Princeton, NJ. After more than 40 years of federal service, Morris Bender, research scientist for hurricane modeling and science at GFDL, recently retired. At the same time, the GFDL Hurricane Model, which has served as an operational forecasting tool for the National Weather Service […]
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 […]
Heather Holbach attended the annual International Ocean Vector Winds Science Team Meeting at the Scripps Institute of Oceanography in La Jolla, CA from 2-4 May. She presented an invited talk, Reprocessing the Tropical Cyclone SFMR database: Procedures and Evaluation, co-authored with Brad Klotz and Allen Garcia of Florida International University. The paper discussed updated SFMR […]
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 […]
Kelly Ryan presented a seminar titled “Using OSSEs to Improve NOAA G-IV Synoptic Surveillance Targeting for Tropical Cyclones”. Abstract: Aircraft reconnaissance missions remain the only means of collecting direct measurements of marine atmospheric conditions affecting tropical cyclone formation and evolution. The National Hurricane Center tasks the NOAA G-IV aircraft to sample environmental conditions that may impact […]
Dr. Mirzargar presented a seminar on “Uncertainty Characterization, Visualization, and Validation of Ensemble Forecasts Using Data Depth”. Abstract: When computational models or predictive simulations are used, researchers, analysts and decision makers are not only interested in understanding the data but also interested in understanding the uncertainty present in the data as well. In such situations, […]
The Greater Miami Chapter of the American Meteorological Society (AMS) held their meeting Wednesday, April 26, 2017 at the AOML Laboratory. The featured speaker was Dr. Frank Marks, Director of the AOML/Hurricane Research Division. Dr. Marks presented a seminar on “Landfalling Tropical Cyclone Rainfall Distributions”. Abstract: Rainfall-induced freshwater flooding associated with landfalling tropical cyclones (TCs) […]
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 […]
