Paper on a way to initialize idealized hurricane models released online in the Journal of Advances in Modeling Earth Systems

Computer models developed to forecast the weather need to know what is currently happening in the atmosphere and in the ocean, what we call “initial conditions,” each time the model starts. The process of making these initial conditions is known as “initialization.” This study is about a new initialization method for both the atmosphere and …

Photos from our Hurricane Harvey operations

The Hurricane Research Division of AOML conducted a series of Tail Doppler Radar missions into Hurricane Harvey including when it was a Category-Four storm approaching the Texas coast.  While carrying out their duties, our scientists took photographs of the eye of the storm as well as of  those involved in the flights.  You can find …

Paper on how vertical wind shear impacts surface winds in hurricanes published in Monthly Weather Review

Summary: Scatterometers are instruments on aircraft or satellites that are used to measure wind speed and direction at the ocean surface. In this follow-up to a 2016 study, the surface wind in tropical cyclones around the world are studied using a large set of measurements from 2000 to 2011. The impact of tropical cyclone intensity, …

HRD Monthly Science Meeting of June 2017

HRD researchers at 71st Interdepartmental Hurricane Conference/Tropical Cyclone Research Forum, Miami, FL – 14-16 March 2017

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 …

New and Improved SFMR data set

The technique to process data from the Stepped Frequency Microwave Radiometer (SFMR), which observes surface wind speeds and rain rates within tropical cyclones, was upgraded prior to the 2015 hurricane season on all NOAA and Air Force Reserve Command hurricane reconnaissance aircraft. The processing method improves the observations across all wind speeds and rain rates. Brad …

HRD observation team monthly meeting – 16 February 2017

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 …
