Tasked by both the National Hurricane Center (NHC) and the Environmental Modeling Center (EMC), NOAA aircraft reconnaissance continues into Hurricane Zeta on October 28, with routine missions taking off from Lakeland, FL at 4 AM EDT. Hurricane scientists supporting these flights assessed Zeta’s wind and precipitation characteristics as the circulation emerged over water after making […]
Dr. Lidia Cucurull, Supervisory Physical Scientist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory, has been appointed the NOAA lead for Goal 2 of the NASA-NOAA Modeling Collaboration. The goals of the Collaboration are to coordinate and focus initiatives and establish a mechanism to transfer important research to operations for Earth Science (including weather) and Space […]
Data from NOAA and Air Force Hurricane Hunter aircraft contributed to the National Hurricane Center (NHC) upgrading Zeta to a hurricane on Monday, October 26. AOML scientists supported all the NHC and Environmental Modeling Center (EMC) tasked P-3 and G-IV missions by processing and sending data for use by specialists and ingestion into numerical models. […]
NOAA P-3 and G-IV aircraft continued flights in and around Tropical Storm Zeta over the weekend at the request of the National Hurricane Center (NHC). AOML scientists supported missions by quality controlling and transmitting data from the Tail Doppler Radar and dropsondes. Data were used by NHC forecasters to understand the current structure of the […]
The National Hurricane Center (NHC) has requested the NOAA P-3 aircraft to investigate recently declared Tropical Depression 28 in the Caribbean Sea. Flights began Saturday October 24 at noon EDT with follow-on flights repeating every 12 hours through Tuesday morning. AOML scientists are processing Tail Doppler Radar (TDR) data for forecasters and weather models. No […]
Summary: It is difficult to accurately forecast how strong a tropical cyclone will get, what we call intensity. The biggest problem is in forecasting when the intensity increases dramatically in a short period of time, or rapid intensification (RI). This study looked at the relationship between how fast a tropical cyclone intensifies and the amount […]

In a new study published in Atmosphere, hurricane scientists looked at how turbulent mixing in the boundary layer affects the intensity and structure of hurricanes in NOAA’s Hurricane Weather Research and Forecasting (HWRF) model. They found that turbulent mixing affects where thunderstorms in hurricanes occur, and how fast air flows towards the center of a storm. Read […]
AOML scientists and collaborators met every weekday between mid-July through mid-October of the Atlantic hurricane season to discuss the tropical forecast and potential opportunities to conduct research. The final week of discussions was led by Kelly Ryan of the Cooperative Institute for Marine and Atmospheric Sciences at the University of Miami. The primary topic of discussion in […]
Because of ongoing Hurricane Delta missions October’s science meeting consisted of only one presentation: Kathryn Sellwood – HRDOBS: A Comprehensive, Research Quality Tropical Cyclone Centered Data Set The presentation is available on the anonymous ftp site at: ftp://ftp.aoml.noaa.gov/hrd/pub/blog/meetings/2020/Science/HRD_SciMeet_20201008.zip
