The expected impacts of climate change on hail vary markedly from region to region, according to a new international study by the University of New South Wales (UNSW).
Scientists conducted an international study and found that the strength of hail may increase in some regions of the world due to global climate change. A review article published in Nature Reviews Earth & Environment examined the impact of climate change on hail in the future.
The frequency of hail thunderstorms appears to decrease in East Asia and North America, while it will increase in Australia and Europe. At the same time, the strength of the hail itself will increase in most regions of the Earth. The review included researchers from the University of Bern, University of Central Michigan, Karlsruhe Institute of Technology, Illinois and Colorado universities, and Peking University.
“We found that the overall threat of hail could increase in Australia, especially in southeastern Australia, including the Sydney area,” explains Tim Raupach, lead author and researcher at UNSW’s Sydney Climate Change Research Center.
However, the researchers note that the current and future impacts of climate change on hail remain unclear, in part due to a lack of long-term observations and limited model studies.
The study examined how the atmospheric components that influence hail – unstable atmosphere, wind shear, or variance and other metrics – would change with climate warming and affect hail.
