Lightning is a natural phenomenon that suddenly flashes in the sky and occurs with a massive discharge of energy. This impressive natural event, which fascinates people, can also lead to dangerous consequences. So, how do lightning strikes form?
Formation of Lightning
Lightning occurs as a result of the sudden discharge of electrical charges between clouds or between a cloud and the ground. The process of lightning formation can be explained as follows:
Charging of Clouds
In storm clouds, collisions occur between water droplets and ice crystals as warm air rises. These collisions cause the separation of electrical charges within the cloud. Typically, the top of the cloud becomes positively charged, while the bottom becomes negatively charged.
Electrical Difference Between the Ground and Clouds
The negatively charged bottom of the cloud causes an accumulation of positive charge in areas close to the ground. The difference between these electrical charges creates a potential energy source.
Electrical Discharge
When the difference between the electrical charges reaches a certain point, this energy discharges, resulting in lightning. This discharge releases light and heat. The sudden expansion at the moment the lightning occurs causes thunder.
Types of Lightning
Intra-cloud Lightning
The most common type of lightning, occurring as a discharge of electrical charges within a cloud.
Cloud-to-Cloud Lightning
Occurs when electrical charges discharge between two different clouds.
Cloud-to-Ground Lightning
It is the discharge of electrical charges between the cloud and the ground. This type of lightning can generally have more dangerous consequences in residential areas.
Positive Lightning
A rarer and stronger type of lightning, usually forming from the top of the cloud to the ground. Positive lightning can be longer-lasting and more powerful.
