Hailstones are formed during thunderstorms, when raindrops are propelled into very cold parts of a cloud, where they freeze. Once the particles are heavy enough, gravity pulls them back towards Earth. As they plummet, they grow into hailstones, which can cause injury to people and significant damage to homes and cars.

3D scans of giant hailstones reveal surprising discoveries that could help predict future storms

In 2022 Girona experienced a disgrace related to hail. It was August 30 and, without warning, balls of 12 centimeters in diameter and about 800 grams of weight began to fall. Unfortunately, a baby died when it was reached by one of the hails. In March of this year, a work published in Geophysical Research Letters supported that, in fact, the abnormal size of these hails was influenced (in part) by anthropogenic climate change, in other words: th…

Why scientists scanned giant hailstones in a dentist's office

Many people also fear large hailstones during thunderstorms. CT scans show how these chunks of ice grow and reach dangerous dimensions.

Im Gewitter fürchten viele Menschen auch große Hagelkörner. Aufnahmen aus Computertomografen zeigen, wie diese Eisbrocken wachsen und ihre gefährlichen Dimensionen erreichen.

Weather: How extreme hailstones grow

(Photo by Emanuel Neacsu via Unsplash) By Stephen Beech via SWNS Hailstones could help forecast future storms, suggests a new study. Spanish scientists used state-of-the-art CT scanning technology to learn more about the hidden anatomy of giant hailstones. They believe the insights they gained can provide new information that may help mitigate damage as more giant hail storms are expected in the future. The research team explained that the stone…

How studying hailstones could help forecast future storms

Hail! Very annoying if you have to cycle through it and impossible if the stones get really big, yet researchers in Spain learned to fathom new secrets with the help of CT scans and hailstones up to 12 centimeters in size During a severe summer depression in 2022 in the north-east of Spain, hailstones up to 12 centimeters in size fell. This […] More science? Read the latest articles on Scientias.nl .

Hagel! Heel vervelend als je er doorheen moet fietsen en ondoenlijk als de stenen écht groot worden, toch leerden onderzoekers in Spanje nieuwe geheimen te doorgronden met behulp van CT-scans en tot 12 centimeter grote hagelstenen Tijdens een zware zomerdepressie in 2022 in het noord-oosten van Spanje vielen hagelstenen tot wel 12 centimeter groot.

Hailstones: Put them through a CT scan and they turn out to be surprisingly layered

International researchers have put giant hailstones through CT scans to get a better look at how they grow, in a study they say could help the world prepare for future extreme hailstorms. In 2022, Catalonia was hit with an extreme storm with hailstones as large as 12cm in diameter wreaking havoc. Local residents saved some of the hailstones in their freezers, and the researchers took some to put through a CT scan as part of a new strategy of stu…

What was the reason for scientists to scan giant hailstones in a dentist's office?

In August 2022, residents of Catalonia were surprised by a rain of unusually large icy projectiles that bombarded northeastern Spain, causing physical injuries to dozens of individuals and widespread property damage. Samples collected in the aftermath of the incident, recognized as the most severe event involving a hail-bearing supercell ever recorded in the region, are now offering clues toward understanding how hailstone formation of such extr…
