Does lightning travel from the earth to the sky, or from the sky downward? Lightning travels both ways. Lightning is a huge electrical discharge that results from vigorous motions that occur in thunderstorms. Lightning can travel from cloud to cloud, within the same cloud, or between the cloud and ground. In-cloud lightning discharges are more common than cloud-to-ground discharges and are not as hazardous. Cloud-to-ground is the best known type of lightning and it poses the greatest risk.
Ground-to-Cloud Lightning. Ground-to-Cloud Lightning. Ground-to-Cloud lightning (sometimes called Upward-moving lightning) is a discharge between cloud and ground initiated by an upward-moving leader originating from an object on the ground.Ground-to-Cloud lightning strikes are common on tall towers and skyscrapers.his is typically caused by wind blowing the lightning channel sideways during the exposure. The stronger the wind and closer the lightning strike, the more horizontal displacement will exist on the recorded image. Camera movement during the capture of a lightning photograph can also result in the same effect.
