The NOAA flight season began early this year with an operational flight into a system, known as Potential Tropical Cyclone 2, that may soon develop into a tropical depression east of the Windward Islands. The plan for the season was recently released and is available online at https://www.aoml.noaa.gov/2022-hurricane-field-program/, and a kickoff meeting to discuss plans … Continue reading NOAA Hurricane Field Program begins with flights into Potential Tropical Cyclone 2 in the Tropical Atlantic

The study introduces a new database that is freely available and consists of over 900 airborne Doppler radar analyses collected between 1997–2020. We demonstrate the capabilities of the database by identifying how the structure of hurricanes changes depending on the strength of the storm, which provides a foundation for future research avenues and computer model … Continue reading Paper describing large new airborne Doppler radar dataset in tropical cyclones released online in Monthly Weather Review
This study uses NOAA airborne Doppler radar data to tie together the many different characteristics of convective rainband updrafts that have been documented, both by observations and from modeling studies. The results help shed light on how these updraft circulations are organized and what underlying dynamics might contribute to the observed organization. You can access … Continue reading Paper on observations of updrafts in hurricanes from NOAA Hurricane Hunter aircraft published in The Journal of Geophysical Research
February's science meeting, co-hosted by the National Hurricane Center (NHC), provided an update on developments of the Hurricane and Ocean Testbed (HOT), a new facility at NHC dedicated to facilitating the transition of research and development projects to operations in a physical space. For many years, NHC partnered with NOAA’s Office of Oceanic and Atmospheric Research via … Continue reading HRD Monthly Science Meeting of February 2022
For the first time, near-surface observations obtained by small Uncrewed Aircraft Systems (or drones) in a major hurricane (Hurricane Maria of 2017) were utilized in a state-of-the-art computer. Such observations are impossible to obtain using regular hurricane hunter aircraft. Furthermore, a new technique to identify and eliminate observations that may not be useful in improving analyses or … Continue reading Study on using hard-to-obtain observations from uncrewed aircraft in Hurricane Maria to improve analyses and forecasts published in Monthly Weather Review
Congratulations to everyone!
This study showed that a weak, disorganized tropical system in an environment that is not primed for intensification can develop a new center where conditions are more favorable for intensification. The ability to observe the center of circulation, the tilt of the vortex with height, the depth of the vortex, the wind shear, and locations … Continue reading Study on how Hurricane Dorian organized before rapidly intensifying published in Monthly Weather Review
34th Conference on Hurricanes and Tropical Meteorology Virtual Meeting The 34th AMS Conference on Hurricanes and Tropical Meteorology was held virtually 10-14 May after being postponed from 2020. This is the premiere meeting for operational and research scientists who work on understanding and forecasting tropical cyclones and other tropical weather around the world. HRD scientist … Continue reading HRD scientists participate in the 34th American Meteorological Society Conference on Hurricanes and Tropical Meteorology
