Investigating vertical wind shear influences on tropical cyclone intensity change

Scientists at NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) and the University of Miami’s Cooperative Institute of Marine & Atmospheric Studies (CIMAS) examine the challenges of accurately predicting when a tropical cyclone will begin a quick and sudden increase in intensity (called rapid intensification or RI) in a new study published in Monthly Weather Review. The paper analyzes a group (ensemble) of computer model … Continue reading Investigating vertical wind shear influences on tropical cyclone intensity change

Study showing how to improve forecasts of rapid intensification released online in Monthly Weather Review

Accurately predicting when a tropical cyclone will begin a quick and sudden increase in intensity (rapid intensification or RI) is a significant challenge. In this study, we analyzed a group (or ensemble) of computer model forecasts of a real RI event to better understand it. To accurately forecast tropical cyclone intensity and when RI will … Continue reading Study showing how to improve forecasts of rapid intensification released online in Monthly Weather Review

NOAA deploys new Altius drone into the eye of Hurricane Ian

Altius-600 uncrewed aircraft system being released from the NOAA WP-3D Orion Hurricane Hunter aircraft during a test flight in June 2022. Watch the video here. NOAA hurricane researchers have added a new tool to their toolbox. For the first time, an Area-I Altius-600 uncrewed aircraft system was deployed into a hurricane by scientists at NOAA’s Atlantic Oceanographic … Continue reading NOAA deploys new Altius drone into the eye of Hurricane Ian

Thirtieth anniversary of Hurricane Andrew’s landfall in South Florida

Hurricane Andrew made landfall on August 24, 1992, near Homestead, Florida, becoming one of the most catastrophic hurricanes in U.S. history. It had an extremely low central pressure of 922 millibars and maximum sustained wind speeds estimated at 165 miles per hour. The storm rapidly intensified less than 36 hours before landfall, leaving most residents less … Continue reading Thirtieth anniversary of Hurricane Andrew’s landfall in South Florida

NOAA Hurricane Field Program begins with flights into Potential Tropical Cyclone 2 in the Tropical Atlantic

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

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 … Continue reading New hurricane research supports advances to NOAA’s 2022 forecasts

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