In the recent years, the world has witnessed fewer but powerful hurricanes more likely due to the warming climate.
"We are seeing fewer hurricanes, but the ones we do see are more intense. When one comes, all hell can break loose," said Professor Jim Elsner, Florida State University, US.
The researchers projected that over the past 30 years, storm speeds have increased on average by 1.3 meters per second or 4.8 km per hour and there were 6.1 fewer storms than there would have been if land and water temperatures had remained constant.
Prior to this research, there had been some discussions among scientists about how warmer ocean temperatures affected the intensity of a hurricane.
Hurricanes can form when ocean waters are 79 degrees Fahrenheit (26.1 degrees Celsius) or more. As the warm water evaporates, it provides the energy a storm needs to become a hurricane.
Higher temperatures mean higher levels of energy, which would ultimately affect wind speed. The researchers said the yearly temperatures can also be a good indicator of what's yet to come in a given storm season.
"In a warmer year, stronger but fewer tropical cyclones are likely to occur. In a colder year, on the other hand, weaker but more tropical cyclones (are likely to occur)," said corresponding author Namyoung Kang, deputy director of the National Typhoon Center in South Korea.
