BOULDER--About twice as many Atlantic hurricanes form each year on average than a century ago, according to a new statistical analysis of hurricanes and tropical storms in the north Atlantic. The study concludes that warmer sea surface temperatures (SSTs) and altered wind patterns associated with global climate change are fueling much of the increase.
The study, by Greg Holland of the National Center for Atmospheric Research (NCAR) and Peter Webster of Georgia Institute of Technology, will be published online July 30 in Philosophical Transactions of the Royal Society of London.
"These numbers are a strong indication that climate change is a major factor in the increasing number of Atlantic hurricanes," says Holland.
