Lightning phenomenon in thunderstorm weather produces ionization.

Lightning phenomenon in thunderstorm weather produces ionization. When the electric field intensity is large enough, it will lead to ionization of molecules in the air and form ionization channels.

1, Introduction to Lightning:

Lightning is a spectacular and somewhat frightening discharge phenomenon accompanied by lightning and thunder. Lightning is usually produced in cumulonimbus clouds with strong convection, so it is often accompanied by strong gusts and heavy rains, and sometimes accompanied by hail and tornadoes. The top of cumulonimbus clouds is generally very high, up to 20 kilometers, and there are often ice crystals on the top of the clouds.

The attachment of ice crystals, the breaking of water droplets and air convection make clouds generate charges. The distribution of charge in the cloud is complicated, but generally speaking, the upper part of the cloud is dominated by positive charges and the lower part is dominated by negative charges. A potential difference is formed between the upper and lower parts of the cloud. When the potential difference reaches a certain level, discharge will occur.

2. Types of lightning:

Lightning can be divided into direct lightning, electromagnetic pulse, spherical lightning and cloud flash. Among them, direct lightning and spherical lightning will cause harm to people and buildings, while electromagnetic pulse mainly affects electronic equipment, mainly caused by induction; Cloud flash occurs between two clouds or on both sides of a cloud, so it does the least harm to human beings.

Matters needing attention in thunderstorm weather:

1, safety of residence:

When thunderstorm weather comes, it is best to stay indoors in a safe place. Avoid staying in tents, shacks or other open areas without shelter, and stay away from objects that are easy to attract lightning, such as metal structures, tall trees or telephone poles.

2. Stay away from water:

The most dangerous place in thunderstorm weather is the water area, because water can conduct electricity. Avoid swimming, fishing or approaching lakes, rivers, oceans and other waters during thunderstorms. If you are on board, return to land as soon as possible in bad weather.

3. Avoid using electrical equipment:

Avoid using electrical equipment during a thunderstorm, especially equipment with a metal shell. Electrical equipment will attract lightning and increase the risk of electric shock. If you are outdoors, put electronic devices such as mobile phones into waterproof bags and ensure that the waterproof bags are well sealed. Avoid using fixed telephones in thunderstorm weather, because telephone lines will conduct lightning. If you have to talk, you'd better use a mobile phone or wireless phone.
