WebWhen the negative charge near the bottom of the cloud becomes large enough to overcome the air's resistance, a flow of electrons - the stepped leader - rushes toward the earth. As the electrons approach the ground, a region of positive charge moves up into the air through any conducting object, such as trees, buildings, and even humans. http://www.atmo.arizona.edu/students/courselinks/spring08/atmo336s1/courses/fall19/atmo170a1s1/lecture_notes/nov26.html

WebAs a result, the ground discharge (upward leader) begins moving up, meeting the downward leader above the ground level – this could be anywhere between 10’s of metres to 100’s of metres above the ground. When this occurs, a low impedance path to the ground is created and the strike occurs.
