Rare Upwards Lightning Caught on Video

A rare capture of lightning striking from the ground up has been caught on video by a University in Florida of Technology.

It was first spotted in the Tropical Storm Dorian in August of 2013. (Video Below)

A total of seven captures of this amazing phenomenon was caught on film.

When a stepped leader approaches the ground, the presence of opposite charges on the ground enhances the strength of the electric field.

The electric field is strongest on grounded objects whose tops are closest to the base of the thundercloud, such as trees and tall buildings.

If the electric field is strong enough, a positively charged ionic channel, called a positive or upward streamer, can develop from these points. This was first theorized by Heinz Kasemir.

As negatively charged leaders approach, increasing the localized electric field strength, grounded objects already experiencing corona discharge exceed a threshold and form upward streamers.
