This is really beautiful - especially all the branching and arcing that occurs before ground contact is made and the main discharge occurs.

Yep! Fake as all get-out! :rofl: Apparently, the cynical expert has never heard of chip bloom and doesn't know that camera sensors produce artifacts when overloaded. The change in dynamic range after the ground-hit (when max current was passing) must have been incredible - I'll bet that's one $$$$ camera.LightbulbSun said:Yeah, anything on there is always considered a fake. If I ate a sandwhich in slow motion, they would say that was all an effect too. Awesome video by the way!
Defennder said:It makes me wonder why lightning zig-zags instead of following a straight path or a smooth arc, or a combination of both.
Yes, that was what made me go gaga too. I saw this is on a show once, an animation of exactly that sequence of events. Many, many plasma steamers would randomly make their way through the air, ionizing it as they went. One streamer would reach the ground, establishing a continuous path of ionized air all the way from cloud to ground, and then wham! the bolt would flow from the ground to the cloud (not from cloud to ground). You can even see in the video the secondary flows of electricity after the first, as the charges balance.tribdog said:You see how all the little branches wiggle around until one touches the ground and the hard strike follows that path.

Awesome. Awesome.
During the morning of May 31, 1998 a warm front moved quickly north across the region. Rapid destabilization occurred during the afternoon as a cold front pressed south toward the region. Lines of severe thunderstorms formed and moved rapidly east across New York and Western New England. Several of these storms became tornadic over Saratoga, Albany, Rensselaer, and Washington counties in New York and Bennington county Vermont. Straight line wind damage occurred in most counties of NWSFO Albany's County Warning Area. Cloud to ground lightning rates over the region reached 15,000 strokes per hour, rates not observed before over this region.

It was like the finale of a fireworks show, just constant lightning strikes. I was only 9 then and I was scared to death because we did have a tornado warning for our county and an F3 tornado just missed us by about 8 miles to the east of us.

4.15 * 60 = 250
250 * 60 = 15,000
I'm right and the others are wrong.
A lightning strike is caused by an electrical discharge between a cloud and the ground, or between two different clouds. This discharge is a result of the buildup of electrical charges within the clouds and the surrounding air.
To capture slo-mo footage of lightning, high-speed cameras are used. These cameras can record thousands of frames per second, allowing for slow-motion playback of the lightning strike.
Filming lightning strikes can be dangerous, as it involves being in close proximity to the strike. It is important to take proper safety precautions and to avoid filming in open areas during a thunderstorm.
Scientists use a variety of techniques to study lightning, including high-speed cameras, lightning mapping systems, and satellite imagery. They also conduct experiments in controlled environments to better understand the physics of lightning.
While scientists have made advancements in predicting the likelihood of lightning strikes, it is still a difficult and unpredictable phenomenon. Lightning can strike anywhere within a thunderstorm, and it is important to always take proper safety precautions during a storm.
