Bernadette Woods Placky, chief meteorologist at NGO Local weather Central, mentioned Helene “had a lot depth” that it might take time for it to lose power, however the “storm was transferring quick … so it may go farther inland fairly shortly.”
This examine utilised three methodologies to look at the three elements of the storm, and was carried out by researchers from the US, the UK, Sweden and the Netherlands.
To check its rainfall, researchers used an strategy based mostly on each statement and local weather fashions, relying on the 2 areas concerned: one for coastal areas like Florida, and one other for inland areas just like the Appalachian mountains.
In each circumstances, the examine discovered precipitation had elevated by 10 per cent due to international warming, which is at the moment at 1.3 levels Celsius above pre-industrial ranges.
To check Helene’s winds, scientists checked out hurricane knowledge courting again so far as 1900.
They decided Helene’s winds had been 11 per cent stronger, or 21kmh, because of local weather change.
Lastly, the researchers examined the water temperature within the Gulf of Mexico, the place Helene fashioned, discovering it was round 2 levels Celsius above regular.
This report temperature was made 200 to 500 occasions extra possible because of local weather change, the examine asserts.
Hotter oceans launch extra water vapor, offering extra vitality for storms as they kind.
“If people proceed to burn fossil fuels, the US will face much more harmful hurricanes,” Clarke warned in a press release.
