Lightning
Lightning is the discharge that usually occurs during a thunderstorm. This electrostatic discharge occurs between a cloud and the ground, between two clouds, or within a cloud.
- First, the air becomes ionized — a plasma — and this acts as the conductor for the lightning.
- Next, jagged bolts — step leaders — provide the lightning’s conductive path.
- Electric current flow, heat, and a shock wave — what we hear as thunder — result.
- Sound thus thunder travels roughly 1 mile every 4.5 second
You may have heard that Florida is the lightning capital of the world. More accurately, Florida is the lightning capital of the United States. According to meteorologists, that distinction of lightning capital of the world belongs to the Democratic Republic of the Congo village of Kifuka.
It should be no surprise that lightning has been recorded on other planets. Jupiter and Saturn exhibit lightning, whereas astronomers believe that have detected lightning in the thick atmosphere of Venus.
