New study on how changes in ocean temperature near the coast during landfall can intensify hurricanes released online in Geophysical Research Letters

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 …

Paper describing large new airborne Doppler radar dataset in tropical cyclones released online in Monthly Weather Review

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 …

New hurricane research supports advances to NOAA’s 2022 forecasts

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 …

HRD participates in the 24th AVAPS™ Users meeting

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 …

HRD Seminar – Alex Mitchell (University of Albany/SUNY) – 6 May 2022

Alex Mitchell presented a seminar titled “The Governing Dynamics and Predictability of Recurving EPAC Tropical Cyclones”. ABSTRACT:  Infrequent recurving eastern North Pacific (EPAC) tropical cyclones (TCs) can threaten life and property along the West Coast of North America primarily through flooding associated with heavy rainfall. These recurving EPAC TCs are most likely to occur during …

HRD Seminar – Prof. Lance Bosart (University of Albany/SUNY) – 6 May 2022

Prof. Bosart presented a seminar titled “Impact of Recurving WPAC and EPAC Tropical Cyclones on Extreme Weather and Wildfire Events over the Western CONUS in Late Summer 2020”. ABSTRACT: Persistent upper-level ridging over the Rockies and an unusually weak summer monsoon that failed to bring much needed rain to the parched Southwest further favored extensive …

Study on forecasting the important area closest to the surface in hurricanes published in Weather and Forecasting

Forecasting turbulence is important in forecasting tropical cyclones (TCs). Turbulence is made up of random and continuously changing wind, in small areas 100 m or less across, but meteorologists forecast TCs using computer models on grids with each point several kilometers from each other. As turbulence is much smaller than these grids, it is typically …

HRD Monthly Science Meeting of April 2022

April's science meeting consisted of two presentations: Sim Aberson: The polygonal eyewall of Hurricane Fabian Robert Rogers: Characteristics of Aligning Weak Tropical Cyclones  Copies of the four presentations are available here.

HRD Monthly Science Meeting of March 2022

March’s science meeting consisted of four presentations by students of our collaborator Prof. Haiyan Zhang at Florida International University: Xinxi Wang: Relating Tropical Cyclone Intensification Rate and Inner-Core Features Using 16-yr TMI data Adrian Lopez: Defining Tropical Cyclone Rapid Intensification Using Bootstrapping Extreme Threshold Estimation  Oscar Guzman: Climatology of Tropical Cyclone Rainfall Magnitude at Different …
