In Argentina, a record high hail fell. The diameter of hailstones exceeded 23 cm

In Argentina, a record-breaking hail fell – hail diameter reached 23 cm. This is stated in a study by scientists from the University of Pennsylvania who described a natural phenomenon in an article for the journal Bulletin of the American Meteorological Society.

Hail usually occurs during violent storms that produce strong, steady updrafts. Winds hold hail above the earth long enough so that it can grow at sub-zero temperatures in the atmosphere. According to scientists, predicting the size of the city is still a daunting task.

The storm, during which a gigantic hail fell, took place on December 27, 2018, in the central province of Cordoba. The diameter of hailstones ranged from 18.7 to 23.6 cm – this is a new world record. So far, the largest hail with a diameter of 20.3 cm was considered, which fell near the city of Vivian, South Dakota.

In the course of the work, the researchers analyzed photos published by eyewitnesses on social networks, and also conducted several interviews with residents of the province.

“Such a well-observed case is an important step forward in understanding the surroundings and the storms that produce the gigantic hail. Ultimately, this will allow scientists to anticipate such extreme events. A giant hail can be very common, and scientists need the help of volunteers who will publish photos of hailstones along with a ruler and measure its length””.
