The Most Interesting Facts about Hail Will Surprise You!
What Is Hail? What Size Can It Be? How Is It Dangerous?
Hail is a type of precipitation consisting of spheres of sleet covered with a crust of ice. Hailstones can be from 5 mm to 20 cm in diameter. For humans, hail is dangerous in several ways:
- physical harm to a person in an open area (bruises, abrasions);
- damage to property (damage to cars, greenhouses, shop windows, tin structures);
- damage to agriculture (beatings of crops, scrapping of plantings);
- damage to livestock (death of poultry and small livestock).

How Does Hail Form?
During a storm, storms throw raindrops into the very cold parts of the atmosphere, causing frost and hail to form. After that, it comes into contact with liquid droplets that freeze on the filled surface. The sudden freezing of water during hail storms creates dark ice in the form of bubbles trapped in the newly formed ice. However, when the water freezes slowly, bubbles escape and new ice becomes transparent. When the approaching storm becomes unbearable, it rains hail. This could be due to the rock being big enough or the depletion being weak. Do you want to know more hailstorm facts, don’t you?! Go ahead!
If hail is exposed to varying temperatures and conditions of liquid water content during a thunderstorm, the hail can have a clear, cloudy layer of ice. The conditions encountered by hail can change if the hail is horizontal in or near an updraft. However, layers are not only created by hail that circulates up and down in a thunderstorm. The wind in a thunderstorm is not limited to the top and bottom. Interesting hail facts waiting for you below.
Horizontal winds come from rotating updrafts like a supercell storm or horizontal winds from the area. Hailstones do not grow even in a storm. At very high altitudes, the air is cold enough (less than -40 ° F) and all liquid water turns to ice. Hailstones require liquid water to grow to a substantial size.
Scientific Facts about Grad TOP-20
- In 1863, the hailstorm on the island of Zealand was so great that it broke through the roofs of houses and even ceilings.
- Sometimes stones, pieces of wood, etc., fall out along with the hail (in July 1892, much small fish fell together with rain and hail in Bosnia).
- In tropical and polar countries, hail is rare.
- Hail is less frequent over the sea than overland.
- The speed of hail falling can be 70 km / h or more.
- Almost always, hail falls before or at the same time, and seldom after.
- The fight against hail is based on the introduction of a special reagent (lead iodide or silver iodide) into the hail-hazardous cloud, which helps to freeze the supercooled drops (the reagent is introduced using rockets or projectiles into the supercooled part of the cloud).
- Even in ancient times, people knew these hail facts and information: a loud sound prevents the appearance of hail or causes the appearance of smaller hailstones, and therefore bells were rung, and/or cannons were fired to save crops.

How to Behave during Hail?
- Hide in hail-protected shelters (houses, apartments, stables, caves, cars).
- Say hello to animals and birds especially easily.
- Cover the car in the garage or shed.
It Is Important to Know about Hail! WHEN IT IS AS BIG AS a GOLF BALL, CLOSE
The easiest way to convey the size of the hail is to compare it to your everyday ones. An inch of hail is about a quarter the size of the United States. 1.5 inches of hail is the size of a ping pong ball. When it reaches 1.75 inches in diameter, it is called a golf ball size hail. This is a very dangerous case. Baseball-sized hail sounds like sparks when hitting at 2.75 inches in diameter and large enough to fit a hole in the floor. When you reach the size of a grapefruit (4″) or softball (4.5″), you need to head underground until there is a storm. Fortunately, these samples are rare.
Major grapefruit hail storms or major hail storms are responsible for only 0.5% of all hail recorded in the last 60 years.
In July 2010, there was the worst snowfall ever in a small town in South Dakota. He crashed into Vivian, was eight inches tall, and weighed about two pounds. For some, it’s the size of a volleyball. The supercell that produced the pistachios created a small hurricane that blows at a speed of 80 km / h.
How does hail fall to the ground?When it becomes heavy enough to overcome the rising force of a thunderstorm, hail will fall and gravity will be pulled to the ground. These are very important scientific facts about hail. Large hail is usually closer to a rising outflow than a small hail because small hail can be blown by a current rising due to horizontal winds. If the wind near the surface is strong enough, the hail can fall diagonally or almost sideways! Hail can tear down the side tracks of a house, smash windows and blow away the house, smash the windows on the sides of the car, and cause serious injuries or death to people or animals.
