The paper discusses changes to the structure of Hurricane Earl (2010) as it rapidly intensified. It found Earl tilted with height before it intensified, but was upright during the intensification. Strong thunderstorms played a significant role in the rapid intensification of Hurricane Earl. Thunderstorms located on the inside of the eyewall are a condition favorable for […]
Hurricanes sometimes change intensity very quickly, and if this happens when they approach land, it can suddenly cause a lot of damage or kill many people. This so-called Rapid Intensification (RI) is very hard to forecast. For the first time, the Hurricane Weather Research and Forecast (HWRF) model that NOAA uses to forecast where a […]
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 […]

January’s Science meeting consisted of 7 of the 9 presentations made by AOML/HRD researchers at the 95th AMS Annual Meeting held in Phoenix, AZ from 4-8 January 2015: Bachir Annane (from a poster): Impact of CYGNSS Data on Hurricane Analyses and Forecasts in a Regional OSSE Framework Javier Delgado: Improving the Performance of the Basin […]
Here is a list of anniversaries relating to tropical cyclones (just those ending in 5 or 0) we will be noting this year. 2015 Hurricane-Related Anniversaries 2010 5th anniversary NOAA adds 12 hours to its hurricane watch and warning lead times. References to storm surge heights are removed from the Saffir-Simpson scale. NASA runs its […]
Three HRD scientists (Drs. Sundararaman Gopalakrishnan, Thiago Quirino, and Frank Marks) along with several National Weather Service (NWS) colleagues won a Department of Commerce Gold Medal for developing and implementing the high-resolution Hurricane Weather Research and Forecast System (HWRF) model, a major advance in operational hurricane intensity prediction. The highest honor bestowed by the Secretary […]
