Abstract
The space-charge calculation of a lightning stroke according to Golde results in a simple geometrical relation between the area within which a flash strikes an object and its height. A comparison between the number of lightning strokes to chimneys and the number of lightning downstrokes per km2 shows, that the statistical attraction distance of a 70 m high chimney is more than 250 m and thereby more than the leader's step-length after Schonland. An explanation may be the space-charge plume, which leaves the lightning rod in a thunderstormfield and may conduct a lightning discharge to the chimney from some hundreds of meters' distance.
