By the 27th, a team from Okinawa Institute of Science and Technology Graduate University summarized the analysis results that the power of hurricanes that occurred in the Atlantic Ocean is becoming less likely to decline as global warming progresses. The cause is that water vapor, which strengthens the destructive power of hurricanes, is easily taken in from the sea due to the rise in sea surface temperature. Therefore, even after landing, the power will continue to be strong, and there is a risk that damage will increase in the inland area.

The team analyzes the transition of power from the observation data of 71 hurricanes that occurred on the North Atlantic Ocean from 1967 to 2018.

Examining the changes in seawater temperature during the same period, it was found that the higher the seawater temperature, the longer it takes for the hurricane to weaken after landing.
