The Constellation Observing System for Meteorology, Ionosphere, and Climate COSMIC) is a set of satellites launched in 2006 that orbit the earth about 500 miles above ground. They use radio signals from Global Positioning System (GPS) satellites in a process called “radio occultation” to accurately measure temperature and moisture at a large number of points in […]

Dr. Delgado and Ms. Bucci presented a seminar on “A 2 km Basin Scale Nature Run for a Hurricane Regional OSSE System“. Abstact: A realistic Nature Run is the foundation to a useful Observing System Simulation Experiment (OSSE) framework. A high-resolution, Basin Scale Nature Run (BSNR) using the Non-hydrostatic Multiscale Model on the B grid […]
Summary: The new National Aeronautics and Space Administration CYclone Global Navigation Satellite System (CYGNSS) measures wind speed on the ocean surface. Because hurricanes happen over oceans where other wind data are usually not available, these new observations may be useful in pinpointing their positions and intensities. This study examines whether CYGNSS wind information will improve […]
Kelly Ryan presented a seminar titled “Using OSSEs to Improve NOAA G-IV Synoptic Surveillance Targeting for Tropical Cyclones”. Abstract: Aircraft reconnaissance missions remain the only means of collecting direct measurements of marine atmospheric conditions affecting tropical cyclone formation and evolution. The National Hurricane Center tasks the NOAA G-IV aircraft to sample environmental conditions that may impact […]
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 […]
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. […]
February’s science meeting consisted of 7 presentations: Bachir Annane: Impact of Simulated CYGNSS Ocean Surface Winds on Tropical Cyclone Analyses and Forecasts in a Regional OSSE Framework Mark Leidner (AER): Creating Vector Winds from Simulated CYGNSS Ocean Surface Wind Speed Retrievals Using Variational Analysis Brittany Dahl: Impact of Global Hawk Observing Strategies on Vortex-Scale Tropical Cyclone […]

Presentations: Robert Atlas, Application of Observing System Simulation Experiments to determining requirements for space-based missions Hua Chen, S. Gopalakrishnan, and J. A. Zhang, The Role of Shallow Convection and Deep convection in the Intensity Changes of Hurricanes Evan A. […]
At a recent awards ceremony, HRD Director Frank Marks and AOML Deputy Director Molly Beringer presented recognitions to several employees whose service went above-and-beyond during the past year. Bachir Annane was recognized for comprehensive and timely analyses using the OSSE framework to evaluate the impact of the CYGNSS scatterometer data set on tropical cyclone forecasts. Jun […]
