In the field of meteorology, an electrical storm is defined as a phenomenon that is characterized by constant lightning while it is taking place, which generates great rumblings in the air. Electrical storms are considered dangerous, since in addition to the lightning that is generated, which can reach a person, heavy rains also occur. On the other hand, the characteristic cloudiness in this type of storm is the so-called cumulonimbus, which is of a gray hue, which can reach sizes that double that of a common cloud.

For a thunderstorm to form, it is necessary that there be the presence of humidity, variable air that rises and some element that is capable of mobilizing said air. The procedure for the formation of a thunderstorm is as follows.

First there must be the presence of hot air which must contain water vapor, then said air must rise while maintaining its high temperature, at the same time that it rises, there is a heat transferthat goes from the earth's crust to the atmosphere, then the water vapor must cool down to thereby condense and thus give way to the formation of cloud cover. These clouds have the peculiarity that their upper part has a lower temperature than their lower region, which causes the vapor located in the upper area to transform into pieces of ice that increase in size. Later the temperatures will rise within the clouds, which will create more steam as the cooler winds move from the top of the cloud. For their part, the pieces of ice that formed previously are displaced by the windtowards the top and bottom repeatedly which causes said pieces of ice to collide with each other and sparks are produced, which generates electrical charge in the cloud and lightning to appear.

Like many other phenomena of nature, this one presents a high degree of danger, since the rays that are generated can reach a person, ending their life almost immediately or, failing that, it can fall into a building.
