Abstract

This paper reports the result of observing winter lightnings for three years using a wireless tower on the summit of Mt. Hotatsu in Ishikawa Prefecture (with an altitude of 637 m and a distance of about 8 km to the western seashore) as an observation site. Battery driven lightning surge memory devices were used to measure lightning current waveforms at different parts of the wireless tower and power distribution poles. An automatic stationary camera was used to photograph lightning paths to the wireless tower and a rain radar. The result of the observation may be summarized as follows: about half of the lightnings is of positive polarity and dual polarity; the lightning current having struck the wireless tower flows back into a power distribution pole through the ground; the ratio of lightning on the wireless tower to that on the power distribution pole is 3 to 1; the ratio of lightning on the lightning arrestor on the tower to that on the building is 3 to 7; half of the lightnings on the rain radar has struck directly the radome; and the back-flow ratio of lightning current onto the arrestor in the case of positive polarity is more than double  More>>
