The first thing we are going to do before delving into the meaning of the term hail is to know its etymological origin. In this case, we can state that it is a word that comes from Latin, exactly from “granun”, which can be translated as “seed” or “grain”.
It is called hail to the frozen water that falls from the clouds in the form of grains of different sizes. This is a different precipitation than snow, descending like flakes.
Hail, therefore, is a solid precipitation. It consists of small spheres of ice, with a usual diameter of between five and fifty millimeters. Hail is generated in clouds of type cumulonimbus.
For the formation of hail, there are solid particles that the ascending winds drag towards the interior of the cumulonimbus, where particles of Water. As these particles rise, the temperature drops and freezing occurs. Once the hail has formed, when it reaches the upper sector of the cumulonimbus it falls towards the surface due to its weight.
In some cases, when the hail begins to descend through the cloud, it thaws and becomes liquid. Another updraft can re-deposit it in the upper area of the cloud, where again water is added that freezes. In this way the hail adds layers until, with enough weight, it rushes.
There are some corners of the planet where hail often occurs. Specifically, we can highlight places such as southern Chile, cities like Potosí and Quito, southern Australia, Serbia, Croatia …
Another singularity that is worth knowing about hail is that the clouds that discharge them are very characteristic. Specifically, they are identified because they have vertical shapes and because they are made up of a column of warm, humid air that has the peculiarity of rising in a spiral.
Hail can cause various inconveniences. The fall of these ice spheres can cause injuries in the people Y material damage on the roofs of houses and in cars, for example. This is due to the violence of the impact due to the speed of the fall and the weight of the ice. By accumulating on the surface, hail also causes other disturbances, including difficulties in driving on public roads or blocked drains.
In the same way, we cannot ignore either that hail storms cause a lot of damage in the field since, in addition to being able to injure livestock, they can destroy crops.
It is curious to know that during the Middle Ages people tried to avoid hail storms. What methods were used for this? Well, from firing cannons, because it was believed that their fire could avoid those, to ringing what were the church bells.
However, from that time until now, different methods have been tried to avoid the aforementioned hail storms. However, we cannot ignore that so far none of these have been really effective.
