According tomedia CNET, sports terms are often used to talk about hail, such as golf ball-sized hail, tennis-sized hail, but “volleyball-sized hail” is an unexpected phrase. One of the hailstones may have set a new world record after huge hail stones poured down during a torrential rains in Argentina in 2018. Researchers at Pennsylvania State University took a closer look at the storm and proposed a new classification of more than 6 inches of hail: “huge hail.”
A hailstone recorded in the storm was between 7.4 inches and 9.3 inches (18.5 cm to 23.6 cm) in diameter. The researchers estimated the size of the hail from a photo. The current hail record belongs to a hailstorm in South Dakota in 2010 with a diameter of 8 inches (20 cm).
The team in Pennsylvania examined the collected hail images, interviewed witnesses, and investigated the damage in the central Argentine city of Villa Carlos Paz. “Such an observed case is an important step in understanding the environment and storms that produce huge hail storms, and how to ultimately predict and detect such extreme events,” said Matthew Kumjian, a Meteorologist in Pennsylvania and lead author of a paper on hail published this month in the Journal of the American Meteorological Society.
Hail can cause great damage to houses, vehicles and crops. “It’s incredible,” Kumjian said. “This is the extreme upper limit of the hail you expect. “
