Paper on using aircraft data in hurricane models to improve forecasts published in Monthly Weather Review

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 …

HRD seminar – Tomislava Vukicevic, AOML/HRD – 14 May 2014

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 …

HRD seminar – Kathryn Sellwood, CIMAS and AOML/HRD – 1 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 …

AOML and HRD researchers at 31st AMS Conference on Hurricanes and Tropical Meteorology, San Diego, CA – 31 March – 4 April 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.
