Two common phenomena occur in cases of disturbances, air depressions and weather instability, each of which expresses a particular situation with its own concept, characteristics and reasons behind them. When they meet together, they are called thunderbolt, let us show each one in detail in this article.
Lightning
This term expresses the bright light emitted from the sky strongly and warns of the instability of the weather in the winter, and produces this light from the collision of clouds in the sky one carries the charge of the negative electricity and the other carrying a positive electrical charge, causing the spacing expressed in the form of spark The light is strong, accompanied and followed by the appearance of this strong voice spark that is very similar to the sound of bangs and is called thunder.
Characteristics of lightning The average cloud that is loaded with negative charges reaches about 30 kA while the cloud carries about 500 joules of energy, while the average of the cloud that is loaded with positive charges is 300 mA of power, Fold the average of the previous cloud.
Lightning works to raise the temperature of the air, especially in places close to the area of the formation and form, where the impact of the strike to about 20000 degrees of the equivalent, equivalent to three times the temperature of the sun.
Lightning speeds are tens to hundreds of kilometers per second, and in some cases can reach up to 250 kilometers per second.
There are many types of lightning, some of which is bronchial, barbed, intermittent and full of the cloud of the earth, and vice versa, any of the land of the cloud, and there is thermal lightning, dry lightning, as well as rocket.
In the case of positive or negative charges from the Earth, these and those rising from the surface of the earth are reconciled.
Thunder
This term expresses the strong sound that follows the sound of lightning. This sound is issued in conjunction with the stage of lightning, and varies from the sound of a sharp bang to a low or strong burst sound, also called a hurricane.
Characteristics of Thunder Thunder occurs as a result of a sudden rise in pressure and temperature, and this expansion is the sharp sound waves we hear in some cases of atmospheric instability and air depressions.
The power of a voice is associated with the force of lightning, and the distance that separates the person who hears the sound from the source of the occurrence of thunder.
Thunder is also called the name of the loser, and its occurrence is always linked to the occurrence of lightning and follows it.
