Stronger hurricanes that are reenergised by jet stream winds are twice as likely to cross the Atlantic and wreak havoc in Europe than weaker ones, new research has found.
Atlantic hurricanes generate international attention because of the destruction they can cause across North America and the Caribbean. Just days ago, ex-hurricane Fiona impacted Canada as one of their strongest storms on record. While lesser-known, these cyclones can also wreak havoc in Europe.
The question of why some hurricanes make it to Europe as ex-hurricanes while others don’t has been unclear. The scientists investigated this question by studying 180 ex-hurricanes over a 40-year period, finding that stronger hurricanes are far more likely to reach Europe, and that those encountering strong jet stream winds often reintensify, helping them to move further east.
The study, led by the University of Reading and the National Centre for Atmospheric Science and published today (27 September) in the American Meteorological Society journal, Monthly Weather Review, helps explain why ex-hurricanes impact Europe, which is particularly important as warmer ocean temperatures due to climate change are expected to make hurricanes stronger.
