The lightning and booming was continuous for almost 3 hours. I stayed up until 3:00 AM photographing it. I was exhausted today, but it was worth it. The first three shots are of the same lightning bolt. The TOGA lightning detector is sensitive enough and the camera's shutter speed fast enough that it captured the pulsing of the bolt.

Hahaha I have a bachelor's in computer engineering (which is almost identical to electrical engineering) and I will say this once. "Current" flows from positive to negative because "current" is just a made up idea and has been around forever; it's just a convention. However, electricity flows from negative to positive because electrons have a negative charge and the "negative" source has an excess of electrons that flow to positive source where there is a shortage of electrons.

Back in the good old days when you had to know the proper shutter speed and f-stop to get the desired results, and when you would spend $20 to develop a roll of film that hopefully had at least one great shot on it.

But for the casual viewer.... you can very well see lighting come from the sky where the charge is held.. and it discharges to the ground or upper atmosphere. So... Electron Flow theory is bullshit. http://earthscience.stackexchange.com/questions/580/why-does-lightning-strike-from-the-ground-up Lightning happens when the potential difference between the clouds and the grounds becomes too large. Once the voltage reaches a critical strength, the atmosphere can no longer act as an electrical insulator. First, a stepped leader is created at the base of the cloud which is a channel through which electrons in the cloud can travel to the ground. But while moving towards the ground, it searches for the most efficient(minimum electrical resistance) route possible. It does so by traveling 50-100 meters at a time then stopping for about 50 microseconds, then traveling another 50-100 meters. In this process it also branches out looking for the best route. As the stepped leader gets close to the ground, a positively charged traveling spark is initiated on some tall object (trees, towers etc) on the ground. The traveling spark moves upward and eventually connects with the stepped leader. Once the stepped leader and the traveling spark have connected, then electrons from the cloud can flow to the ground, and positive charges can flow from the ground to the cloud. This is known as return stroke. But this flow unlike the flow from up has a well defined shortest route now. This massive flow of electrical current occurring during the return stroke combined with the rate at which it occurs (measured in microseconds) rapidly superheats the completed leader channel, forming a highly electrically-conductive plasma channel. The core temperature of the plasma during the return stroke may exceed 50,000 K, which makes it shine so bright. Does lightning strike from the sky down, or the ground up? The answer is both. Cloud-to-ground lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts. Objects on the ground generally have a positive charge. Since opposites attract, an upward streamer is sent out from the object about to be struck. When these two paths meet, a return stroke zips back up to the sky. It is the return stroke that produces the visible flash, but it all happens so fast - in about one-millionth of a second - so the human eye doesn't see the actual formation of the stroke. Lightning discharges may occur between areas of cloud without contacting the ground. When it occurs between two separate clouds it is known as inter-cloud lightning, and when it occurs between areas of differing electric potential within a single cloud it is known as intra-cloud lightning. Intra-cloud lightning is the most frequently occurring type. Leadfinger 1 Link to comment Share on other sites More sharing options... Awards
