- As storms linger further over the east coast, they will cause greater damage along the densely populated corridor.
- Hurricanes that produce catastrophic damage similar to Hurricane Sandy in 2012 will be more common.
- The changes in storm velocity will be driven by changes in atmospheric patterns across the Atlantic, caused by warmer air temperatures.
The hurricane season may be over for this year, but a new study released on Monday says the monster storms will create greater chaos in the coming decades, thanks to climate change.
Specifically later in this century, residents of the northeastern United States will see worsening hurricanes as storms arrive faster – but slow down once they land, the study said. Hurricanes that produce catastrophic damage similar to Hurricane Sandy in 2012 will be more common, researchers said.
Hurricane Sandy, known as Superstorm Sandy, smashed into the northeastern United States in late October 2012, killing 159 people and causing $ 78.7 billion in damage, according to the National Oceanic and Atmospheric Administration.
As storms linger further along the east coast, they will cause greater damage along the densely populated corridor, which includes massive metro areas such as Washington, DC, Philadelphia, New York City and Boston, according to the study.
“This study suggests that climate change will play a long-term role in increasing the strength of storms along the east coast of the United States and elsewhere,” said co-author Benjamin Horton, director of the Earth Observatory of Singapore at Nanyang Technological University, in a announcement.
The changes in storm velocity will be driven by changes in atmospheric patterns across the Atlantic, caused by warmer air temperatures.
Researchers found that future hurricanes on the east coast are likely to cause more damage than past storms. The study predicted that a greater number of future hurricanes would form near the east coast, and these storms would reach the northeast corridor more quickly.
The storms will then slow down to a requirement as they approach the east coast, allowing them to produce more wind, rain, floods and related damage in the northeast region. The longest-lived tropical storms are expected to be twice as long as storms today.
And the longer storms last, the worse they can be, said study author Andra Garner of Rowan University in New Jersey.
“Think of Hurricane Harvey in 2017, which is sitting over Texas, and Hurricane Dorian in 2019 over the Bahamas,” she said. “Prolonged exposure may exacerbate the effects.”
