A “volleyball” hail falling in Argentina

A thunderstorm hit the center of the Argentine city of “Villa Carlos Paz” about two years ago with hailstones, and an American research team recently found that one of them exceeded the size of volleyball in size. The hailstones are blocks of ice spherical or irregular in shape, ranging in diameter from a few millimeters to several centimeters, and researchers who investigated in the storm of 2018 found that there is one hail that is likely to reach 9.3 inches, and is likely to set a new world record.
The current record of hailstones indicates that the largest was 8 inches, about the size of a volleyball, and fell into Vivienne, Lyman County, South Dakota, America, but the study published by the research team from the University of Pennsylvania in the latest issue of the Journal of the American Meteorological Society, documented to exceed The hailstone that fell in Argentina of this size.
“It is unbelievable,” said Matthew Kumgian, associate professor in the Department of Meteorology and Atmospheric Sciences, in a report released yesterday by the university’s website.
Scientists suggest that hail greater than 6 inches should be classified as colossal, and they said that raising awareness of these events, while rare, could help to assemble a better understanding of dangerous storms. “Anything greater than a quarter of the size can start putting scratches on your car,” Kumgian added. “In some rare cases, 6-inch stones cause damage to multiple surfaces and floors in homes. We would like to help reduce the impacts on life and property by helping to anticipate these types.” Of events ».
The residents of the Argentine city of “Villa Carlos Paz” had published on social media, photos and videos of hailstones, and the researchers followed up the accounts a year after the storm had occurred, interviewed witnesses, visited the sites where the damage occurred, combining photographic data and analyzing notes Radar, using photogrammetry (taking measurements from photographs) and video evidence, estimated that a hail could have set a world record.
“Such a well-observed state is an important step forward in understanding the environments and storms that produce the huge cold, and ultimately how to anticipate and discover such extreme events, where predicting the size of the cold remains a challenge for scientists,” says Kumgian.
