For decades, meteorologists used dropwindsondes, weather instrument packages deployed from aircraft, to make atmospheric soundings below flight level. Starting in the 1970s they used Omega dropwindsondes (ODWs) that employed the very low-frequency Omega navigation signals to estimate the ODW’s motion relative to the aircraft, and subsequently calculate the wind. Because of the limitations of this system, […]

Twenty-three AOML and HRD scientists participated in the recent 32nd AMS Conference on Hurricanes and Tropical Meteorology in San Juan, PR, as authors or co-authors on 36 presentations and 11 posters. Roughly 650 presentations (452 oral presentations in 70 sessions and 196 posters in 2 session) were submitted to the conference. Of the 440 TC-related presentations […]
Abstracts and recordings of the 19 presentations and 5 posters AOML & HRD researchers presented (or were co-authors) at the 96th AMS Annual Meeting are available online from the AMS website: Presentations: A First Look at the Impact of Coyote UAS Observations from Hurricane Edouard (2014) on Tropical Cyclone Data Assimilation and Prediction – Altug […]
A number of HRD employees were honored at an awards ceremony at AOML earlier in December. Among the honorees: Jun Zhang earned a CIMAS Gold Medal for efforts to improve the surface layer and vertical-diffusion parameterization within the HWRF model to better match the observed surface flux and diffusion. These factors were essential for HWRF to […]
In the early morning hours of October 24, 2005, Hurricane Wilma came ashore on Florida’s Gulf coast. The storm had set records and then ravaged the Yucatan Peninsula prior to this final landfall, but it still had plenty of power left to inflict great damage on southern Florida. The 2005 hurricane season was already one […]
On September 27, 1985, Hurricane Gloria swept over the Outer Banks then rushed across Long Island, New England, and Canada. It was the first significant hurricane to hit New England in twenty-five years and brought heavy rains and high winds to the Mid-Atlantic states as well. Gloria began as a tropical depression over the Cape […]
Early on the morning of September 24, 2005, Major Hurricane Rita came ashore near the Texas/Louisiana border. In the midst of the very active 2005 hurricane season, Rita caused considerable panic as it approached the coast, with scenes of destruction from Hurricane Katrina still playing on TV news programs. It left behind a swath of […]
A long-term (1996–2012), high-quality, high vertical resolution (∼5–15 m) GPS dropsonde dataset is created from NOAA Hurricane flights and consists of 13,681 atmospheric profiles for 120 tropical cyclones. The paper can be accessed at http://journals.ametsoc.org/doi/abs/10.1175/BAMS-D-13-00203.1.
Midday on September 2, 1985, Hurricane Elena came ashore near Biloxi, MS. But it had been anything of a direct path. Elena’s track had many twists that had vexed forecasters and emergency managers all along the northern Gulf coast. Elena began as a disturbance in the deep tropical Atlantic, but hostile conditions prevented it from […]
