Slow Motion X20 Of Cloud To Ground Cg Lightning Lakenham Norwich I have took part of one of the best cg lighting from the storm that hit norwich on thursday night and slowed it day by x20 to create this clip. the program i. A typical cg lightning strike initiates inside the storm. under the influences of the electric field between the cloud and the ground, a very faint, negatively charged channel called a "stepped leader" emerges from the storm base and propagates toward the ground in a series of steps about 160 feet (50 meters) in length and 1 microsecond (0.000001 seconds) in duration.
Slow Motion Cloud To Ground Lightning Youtube Lightning can also be triggered by aircraft flying through strong electric fields. if the plane is below the cloud, then a cg flash could result. in the most common type of cloud to ground lightning (cg), a channel of negative charge, called a stepped leader, will zigzag downward in roughly 50 yard segments in a forked pattern. this stepped. Natural positive cloud to ground (cg) lightning flashes have been studied much less than negative cg and intracloud (ic) flashes. first, positive cg flashes are much less frequent than negative cg flashes; second, the initiation of positive cg flashes usually occurs deep inside the cloud, making optical measurements inefficient to observe the initial characteristics of the downward positive. Cg propagates at a typical speed of 106 m s (zhu et al., 2016); thus, the initiation altitude of this cg flash figure 1. ground measured vlf and lf radio frequency signals of a cloud‐to‐ground lightning flash occurring at 02:23:12.83 ut on 25 july 2019 around the time of a fermi tgf. the gamma ray photon counts are binned in 50 μs. Propagating downward and making a connection to the ground (s. li et al., 2020; wu et al., 2018b). but for cg lightning with a large charge moment, which has the potential to induce sprites at an altitude of 40–90 km above a thunderstorm or upward lightning from tall buildings on the ground, it usually involves.
