Abstract
Many lightning stroke models of summer lightning have been proposed by various researchers up to this time. In Japan, it has been required to establish a new lightning shielding theory which considers upward leaders in winter lightning on the Japan Sea coast.<br> Differrences between lightning progression features of winter and summer lightnings prevent the conventional lightning stroke models of summer lightning from application to winter lightning.<br> Based on lightning observation data and discharge characteristics of long air gaps, a basic model of leader progression was previously proposed by the author. At this time, an improved model (upward leader progression model: ULP model), which considers statistical variation of leader progression, has been developed. This new model can reproduce various lightning features such as distribution of time-to-discharge, the ratio of numbers of lightning stroke to tall structures and so on.<br> Using the ULP model, shielding performances of high structures such as a lightning shielding tower and an overhead ground wire against winter lightning are predicted and compared with field observations.
