The book discusses how to make weather warnings most effective through communication and partnerships. Warnings are the result of a process from weather observations to weather forecasts to hazard forecasts to socio-economic impact forecasts to warning messages to decisions on how to avoid or mitigate the hazard. The book offers a framework across government, private … Continue reading Toward the “Perfect” Weather Warning published

This study uses a state-of-the-art hurricane modeling system developed at the NOAA/Atlantic Oceanographic and Meteorological Laboratory’s Hurricane Research Division, the Basin-Scale Hurricane Weather Research and Forecast (HWRF-B) model, to demonstrate a link between an oceanographic process called coastal downwelling and the intensification of tropical cyclones (TCs or hurricanes) near landfall. We show that coastal downwelling … Continue reading New study on how changes in ocean temperature near the coast during landfall can intensify hurricanes released online in Geophysical Research Letters
This study examines the impact of assimilating Doppler Wind Lidar (DWL) data on hurricane prediction in the operational Hurricane Weather Research and Forecasting system. A series of experiments were conducted to identify the best way to assimilate the DWL data in comparison to assimilation of Tail Doppler radar data. A new data thinning method was … Continue reading Paper on assimilating Doppler wind lidar and Doppler radar data into a hurricane model published in Remote Sensing
The primary goal of NOAA/OAR/AOML’s Hurricane Research Division (HRD) is to improve the understanding and prediction of tropical cyclones (TCs). While this improvement can be accomplished from a variety of approaches, a unique capability of HRD is the routine collection and analysis of airborne observations within the tropical cyclone inner core and its atmospheric and … Continue reading Rob Rogers presents seminar on Advancing the Understanding and Prediction of Tropical Cyclones Using NOAA Aircraft Observations
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 summer during the 2022 Atlantic hurricane season, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) will once again be on the frontlines helping NOAA prepare the public for severe weather. They will also conduct new research on the complex processes of how tropical cyclones form, develop, and dissipate. AOML’s operational missions tasked by NOAA’s Environmental … Continue reading New hurricane research supports advances to NOAA’s 2022 forecasts
The Airborne Vertical Atmospheric Profiling System (AVAPS™) is held annually by the National Center for Atmospheric Research (NCAR) Earth Observing Laboratory to discuss Science, Operations and Dropwindsonde Technology, along with having an open discussions for the different topics. NCAR is sponsored by the National Science Foundation. HRD scientists made two presentations at the recent meeting … Continue reading HRD participates in the 24th AVAPS™ Users meeting
On Saturday, May 14th, AOML's Hurricane Research Division participated in the 2022 Eye of the Storm outreach event at Ft. Lauderdale's Museum of Discovery & Science. HRD scientists answered questions about flying into hurricanes and how the data get into the computer models to improve the forecast. National Weather Service/National Hurricane Center table talked about … Continue reading HRD participates in the 2022 Eye of the Storm outreach event at Ft. Lauderdale’s Museum of Discovery & Science.
We test how different groups of observations, which reach the computer that run weather models at different times, impact the model forecast. We find that by not using the observations that arrive late, the forecast is much worse, showing the importance of quick transmission of observations. Direct observations (those measured within the atmosphere) have a greater … Continue reading Study on the impact of weather data not transmitted in a timely manner released online in Weather and Forecasting
