Last year’s Atlantic hurricane season was undoubtedly devastating, but the bad news is that stronger hurricanes will be part of a continuing trend in the future,media reported. Hurricanes will be stronger — a thought-provoking conclusion from a study led by James Kossin, a scientist at the National Oceanic and Atmospheric Administration (NOAA), at the University of Wisconsin-Madison.
The research paper was published monday local time in Proceedings of the National Academy of Sciences.
The study, which looked at satellite data from 1979 to 2017, found that the maximum sustained winds of tropical cyclones (hurricanes and typhoons) became stronger and stronger over time. “Through modeling and our understanding of atmospheric physics, this study is consistent with what we expect to see in warming like ours,” Kossin said in a press release from the University of Wisconsin-Madison. “
The data suggest that tropical cyclones are more likely to become a category 3, 4 or 5 major storm in the Saffir-Simpson wind scale. Hurricane Dorian, for example, hit the Bahamas in late 2019, a Category 5 storm with sustained winds of at least 157 mph (252 km/h).
It is understood that the 2020 Atlantic hurricane season will begin on June 1, AND NOAA will release its preliminary forecast for the season later this week.
Kossin has been tracking hurricane data for years. A 2018 study he led showed that hurricanes were slowing and local rainfall and flooding were increasing.
And new research suggests that increasingly intense tropical cyclones may indeed be linked to climate change. “This is a good development, and it increases the confidence that global warming is making hurricanes stronger,” Kossin said. However, our findings do not tell us exactly how many of these trends are caused by human activity and how much may be caused by natural changes. “
