Lightning Lapse Series

Hank Schyma provides this series of lapses and stills of lighting. A very electric set of scenes!

Upward-directed Lightning

Tom Warner of ztresearch has provided these slow-motion examples of the evolution of upward-directed, tower lightning near Rapid City, SD. Both movies illustrate flashes that were captured by a high-speed camera at an astounding 7,207 frames per second. Regarding the second movie, Tom states: "An upward lightning flash initiated from a TV tower in Rapid City, SD ... the positive polarity leader moves upward and branches into two primary channels. The right channel is weak and develops numerous recoil leaders which try to reionize the decayed branch. At one point the branch sustains growth following a recoil leader connection. The entire video is about 1/2 second."





CG Lightning caught by High-speed Camera

Using a high-speed camera, storm chaser Tim Samaras snagged this very cool CG bolt on 10 July 2011.

Positive CG Lightning

Tom Warner captured this positive cloud-to-ground lightning flash with a high-speed camera -- recorded at 7,207 images per second! As he states: "Weak positive leader branches decay and become cutoff as they propagate downward from the cloud. Fast recoil leaders develop along the decayed branches in an attempt to reionize the branches. The downward positive leader eventually connects with the ground forming a bright return stroke."

"All Alone in the Night" - Another ISS Lapse

David Peterson compiled this series of ISS sequences. Another fine illustration of the peace and beauty of earth from afar.

Slow Motion Lightning

Tom Warner of ZT Research has documented lightning "anatomy" using photographic equipment that can record up to 100,000 framers per second. The video below is an excellent teaching source, revealing the stepped leader in all its glory.


Additional videos may be found on his website here. Animated gifs of similar perspectives may be found on this NWS site. Also, NASA has the same video as above with a bit of context.

"Earth" - an ISS Lapse

Michael Konig created this lapse from sequences of photographs taken by the crew of the expeditions 28 and 29 onboard the International Space Station from August to October, 2011. Shot at approximately 350 km AGL.
