What is lightning between clouds called?
The phenomenon you’re describing is known as intra-cloud lightning. Intra-cloud lightning occurs entirely within a single cloud, jumping between different charge regions within the cloud. It is sometimes referred to as sheet lightning because it illuminates the sky like a ‘sheet’ of light. This is distinct from cloud-to-cloud lightning, which occurs between two or more separate clouds.

How does lightning occur with a cloud?
Lightning occurs when there is a rapid discharge of electricity between the positive and negative charges within a cloud, as well as between the cloud and the ground. In the early stages of development, air acts as an insulator between these charges.

However, as the opposite charges build up, the insulating capacity of the air breaks down. When the insulating capacity is no longer sufficient, a rapid discharge of electricity, known as lightning, takes place. This phenomenon is a result of the electrical imbalance within the cloud and between the cloud and the ground.

What is lightning between clouds and Earth?
Lightning between clouds and Earth involves a typical cloud-to-ground lightning bolt. The process begins with a step-like series of negative charges, known as a stepped leader, racing downward from the bottom of a storm cloud toward the Earth.
This occurs along a channel at a speed of about 200,000 mph (300,000 kph). Each segment of the stepped leader is approximately 150 feet (46 meters) long. This is the initial phase of a lightning strike where the negative charges move towards the Earth, paving the way for the subsequent discharge of electricity.

Can lightning occur without clouds?
Yes, lightning can occur without the presence of clouds directly overhead. The common myth that you’re safe from lightning if it’s not raining or there are no clouds directly above you is not accurate. Lightning can strike more than three miles from the center of a thunderstorm, extending far beyond the area covered by rain or thunderstorm clouds.

This phenomenon is often referred to as “bolts from the blue,” and these lightning strikes can happen at distances of 10-15 miles from the thunderstorm. Therefore, it’s important to be aware that lightning can occur even when the sky seems clear or when there are no immediate signs of a thunderstorm.
