The thunderstorms have been investigated since Benjamín Franklin, two centuries ago, felt that lightning was an electric shock. Despite theoretical and experimental instruments, there are still aspects for which there is no definitive explanation. The following rules are within what is now considered the most plausible explanation.
The thunderstorms occur when there are clouds of vertical growth. These clouds are fundamentally formed by the climb of heated air on the surface, fundamentally liquid, of the earth. The cloud will continue to grow in height while feeding with warm air. If this air is wet, when reaching high areas in which the temperature is low, the water vapor is condensed drops. Water droplets are converted into ice at more height. At the same time, cold air enters the upper area of the cloud, which are more regrettable than the hot down to earth. That is why we have a double circulation, the hot air and the cold air down. Moreover, water droplets and ice pieces have a turbulent movement in the cloud because of the two air flows, until they fall into the earth in the form of rain or hail when they reach sufficient weight. This complex cloud is called cumulonimbo and has enough kilometers high. During this cloud formation process come in and static electrical taxes occur and separate. The positive are at the top and the negatives in the lower. Parallel, the earth’s surface is positively charged through a complex process.
We have all the conditions, almost necessary, so that there is a thunderstorm. The country is positively charged, the lower part of the cumulonimbos loaded negatively and the superior positive. To communicate positive and negative loads, the air between them is needed, which isolates, a driver becomes. This change helps the cloud. The electrical loads generate an electric field around them that when it is intense enough, electrons are able to start atoms and air molecules. It is said that the air has been ionized and made a driver. At that time, millions of cloud electrons travel trillions in milliseconds to the earth in zigzag movements. The paths of electrons are illuminated by a violet glow (lightning) that is typical of ionized air molecules. At the same time in light there is a strong heating of the air (temperatures higher than that of the surface of the sun) that causes its expansion at a very high speed. This expansion is the one who gives rise to thunder. The time that passes from seeing lightning until we hear Thunder enables you to calculate how far the storm is. We have explained the clouds soil rays, but Wolkennube rays can also take place in the cloud, cloud-schedule and Tierra-Nuis. Another day is also the functioning of the lightning bars.
