Early on the morning of August 29th, 2005, Hurricane Katrina made landfall on the Louisiana delta region and the Mississippi coast. The storm surge brought enormous damage to the Gulf Coast and, when the levees around New Orleans failed, a great number of fatalities. Coming amidst the very busy 2005 hurricane season, Katrina brought death … Continue reading 10th Anniversary of Hurricane Katrina
NOAA and U. S. Air Force aircraft have been gathering wind, temperature, humidity and pressure information inside hurricanes for more than 30 years. The NOAA aircraft have been fitted with Doppler radars that can see the entire hurricane's rain and wind from near the ground to the top of the clouds. All the information is … Continue reading Paper on using aircraft data in hurricane models to improve forecasts published in Monthly Weather Review

Dr. Vukicevic presented a seminar on “What is Parameterization Uncertainty and How to Evaluate It for Ensemble Prediction? ” which is available on the NHC science presentation web site or at: http://www.aoml.noaa.gov/general/lib/lib1/nhclib/Powerpoints/TomislaviaVukicevic/What%20is%20parameterization%20uncertainty%20and%20how%20to%20evaluate%20it%20for%20ensemble%20prediction%20-20140513%201858-1.wmv
Tomi presented a seminar on "What is parameterization uncertainty and how to evaluate it for ensemble prediction?" Abstract: It is widely accepted that parameterizations of sub-grid scale processes in Numerical Weather Prediction (NWP) models are uncertain and that this leads to forecast errors. The impacts of parameterization uncertainty have been demonstrated by numerous sensitivity studies in … Continue reading HRD seminar – Tomislava Vukicevic, AOML/HRD – 14 May 2014
Kathryn presented a seminar on: “Vortex Spin-Down and Imbalances During Inner Core Data Assimilation” Abstract: The axi-symmetric component of the tropical cyclone (TC) wind field has been shown via numerical methods and observations to be well approximated by thermal wind balance throughout much of the vortex. When this assumption is valid, it constrains vortex evolution by requiring a secondary … Continue reading HRD seminar – Kathryn Sellwood, CIMAS and AOML/HRD – 1 May 2014
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%, … Continue reading AOML and HRD researchers at 31st AMS Conference on Hurricanes and Tropical Meteorology, San Diego, CA – 31 March – 4 April 2014
