This study examined how the intensity (wind speed) of topical cyclones in the Atlantic has changed over time and how it varies with El Niño and La Niña. In terms of trends, the most intense storms are becoming stronger and the most extreme rapid intensification is becoming more frequent. During La Niña conditions, intensification rates are higher and hurricanes are stronger. Use of better statistical techniques and additional data resulted in reduced upward trends compared to prior estimates and a more comprehensive picture of the impacts of El Niño and La Niña on Atlantic tropical cyclone intensity.
