Global Hurricane Activity at Historical Low

Since 2007, global tropical cyclone activity has decreased dramatically and has continued at near-historical low levels according to FSU professor.

Palm Coast, FL – June 27, 2011 – A peer reviewed paper by FSU’s Dr. Ryan Maue indicates a dramatic reduction in the amount of global cyclonic energy since 2007.


During the past 6-years since Hurricane Katrina, global tropical cyclone frequency and energy have decreased dramatically, and are currently at near-historical record lows. According to a new peer-reviewed research paper accepted to be published, only 69 tropical storms were observed globally during 2010, the fewest in almost 40-years of reliable records.
Furthermore, when each storm’s intensity and duration were taken into account, the total global tropical cyclone accumulated energy (ACE) was found to have fallen by half to the lowest level since 1977.
In his new paper, "Recent historically low global tropical cyclone activity", Dr. Ryan Maue, a meteorologist from Florida State University, examined the last 40-years of global hurricane records and found strikingly large variability in both tropical cyclone frequency and energy from year-to-year. Since 2007, global tropical cyclone activity has decreased dramatically and has continued at near-historical low levels. Indeed, only 64 tropical cyclones were observed globally in the 12-months from June 2010 – May 2011, nearly 23-storms below average obliterating the previous record low set in 1977.
