MODELING OF LIGHTNING INCIDENCE TO TALL STRUCTURES .2. APPLICATION

The present paper comprises an extensive computer investigation of lig htning incidence to tall masts, based on a theory presented in a compa nion paper, for both flat and hilly regions. The investigation covers both downward negative lightning incidence and upward flash from tall masts under negative cloud. The factors investigated include: mast hei ght, statistical distribution of the ground electric field, as well as mountain height and topology. Predicted lightning incidence and proba bility of upward flash are successfully verified against extensive fie ld observations.
