Starting in 2010, the National Aeronautic and Space Administration and the National Oceanic and Atmospheric Administration have used the Global Hawk, an unmanned aircraft that can fly at 65,000 feet for 24 hours at a time, to make observations in tropical cyclones. The Global Hawk can release dropsondes that measure temperature, humidity, pressure, and wind […]

Kelly Ryan presented a seminar titled “OSSE Evaluation of the Impact of Aircraft Observations on Hurricane Analyses and Forecasts” at the NOAA National Severe Storms Laboratory NSSL. ABSTRACT Each year, NOAA/AOML’s Hurricane Research Division (HRD) conducts its Hurricane Field Program in which observations are collected via NOAA aircraft to improve the understanding and prediction of hurricanes. […]
Abstracts and recordings of the 25 presentations and 6 posters AOML & HRD researchers presented (or were co-authors) at the 97th AMS Annual Meeting are available online from the AMS website: Presentations: Bachir Annane, B. D. McNoldy, S. M. Leidner, R. N. Hoffman, R. Atlas, and S. J. Majumdar, Impact of Simulated CYGNSS Ocean Surface Winds […]
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 […]
In October 2015, off the west coast of Mexico, Hurricane Patricia became the strongest hurricane ever recorded in the western hemisphere, intensifying faster than any other storm on record. A unique set of observations were collected in Patricia. National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration/Office of Naval Research (ONR) aircraft […]
