Today Climate.gov posted a Science Brief on recent research findings about the trends in tropical storm activity due to warming ocean temperatures associated with the changing climate. They describe how cyclone intensity has been measured and how it is increasing. They also describe likely changes in the tropical atmospheric conditions in the future and how those changes are expected to move the latitude of greatest intensity farther north.
