In a typical storm cloud, the upper part, made up of ice crystals, is generally positively charged, while the lower part, made up of water droplets, is negatively charged. Through this influence, the lower part of the cloud causes the development of charges of opposite signs (therefore positive) on the ground nearby.
Electrical exchanges occur within this cloud, but also between different clouds of the same type. This results in lightning. However, the cumulonimbus cloud also behaves like a giant flat cloud-to-ground capacitor.

Known since time immemorial, lightning presents numerous dangers to property and living beings. A direct lightning strike is the encounter between a descending leader and an ascending leader originating from a natural trigger.
Up to 100 lightning strikes occur every second on the Earth's surface. Indeed, the study of this phenomenon highlights three main categories of risks
What is the origin of lightning? Formation of lightning bolts, the mechanism of electrical discharge in storm clouds, types of lightning and risks. Understanding this natural phenomenon.
