Why does lightning often occur in ‘double strikes’?
Lightning first comes down in a flurry of haphazard lines trying to find the path of least resistance to the ground. This is called the lead. When the lead finds the path to the ground, you can see a very quick flash move up the lead into the cloud.
The Short Answer
Lightning first comes down in a flurry of haphazard lines trying to find the path of least resistance to the ground. This is called the lead. When the lead finds the path to the ground, you can see a very quick flash move up the lead into the cloud. This return stoke is the full strength of the lightning strike transferring power to the ground, like traffic moving forward at a fresh green light. Once that return stroke makes its trip up the lead, the cloud gives it more energy, making the second flash you see
