Michael Fischer wins the AMS Editor’s Award for the Journal of the Atmospheric Sciences
Michael Fischer, Assistant Scientist with the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) at the University of Miami and at the Hurricane Research Division has been awarded the 2024 Editors’ Award from the American Meteorological Society for The Journal of the Atmospheric Sciences for multiple high-quality and very thorough reviews that have been helpful […]
NOAA completes missions into Major Hurricanes Franklin and Idalia
NOAA conducted 12 P-3 and 5 G-IV operational and research missions into Hurricanes Franklin and Idalia between 21 and 31 August. The NOAA P-3 conducted operational missions to “fix” (observe the location and intensity of) both systems and also Tail Doppler Radar missions to gather data to improve model initial conditions and forecasts. The NOAA […]
Evaluation of rainfall forecasts for tropical cyclones making landfall published in Weather and Forecasting
Rainfall produced by landfalling tropical cyclones (TCs) in HAFS and HWRF-B hurricane models is evaluated by verifying precipitation characteristics, including the shape and size of the rainfall area. Results show that both models produce reasonable rainfall forecasts, but both also tend to forecast storms that are too intense due to precipitation being too close to […]
Study looking at the impact of dropwindsonde data obtained at different distances from the tropical cyclone center published in Weather and Forecasting
An experimental version of the Hurricane Weather Research and Forecasting model (HWRF) is used to conduct the most comprehensive assessment to date of the impact of dropsonde data obtained at different distances from the center of a tropical cyclone (TC) on forecasts. The main finding is that dropsonde data within 250 km of the TC […]
Paper exploring the region closest to the Earth’s surface when a tropical cyclone makes landfall published in the Journal of Geophysical Research Atmospheres
Improved understanding of small-scale processes near the surface is important for advancement of TC intensity prediction. Observational data collected by multilevel towers are analyzed to study the turbulent mixing process and structure in the atmospheric surface layer of two landfalling TCs. Newly derived coefficients may lead to improved forecasts when used in numerical models. Read […]
Recap of NOAA aircraft flights into non-developing African Easterly waves
NOAA recently conducted a series of flights into African Easterly Waves to try to understand why some develop into tropical cyclones and some do not. A quick look at some of the data obtained and some logistical issues is available at https://www.aoml.noaa.gov/ftp/hrd/blog/meetings/2023/6_7Aug_AEWs_Debrief.pptx For more information, contact aoml.communications@noaa.gov.
40th anniversary of Hurricane Alicia
To commemorate the 40th anniversary of Hurricane Alicia’s landfall near Galveston, the National Weather Service Office in Houston/Galveston has created a story map. Details in the story map include the work that NOAA/AOML/HRD did with the hurricane, including multiple flights with Hurricane Hunter aircraft, gathering the first-ever airborne Doppler radar data in a major hurricane, […]
