Abstract: Ground flash density, lightning current steepness and small current percentage were selected as the indexes to classify lightning hazard intensity by using the lightning detection data from 2007 to 2016 in Hubei province. The weight of each index and the classification model of lightning hazard intensity were determined by projection tracking. By using the natural breakpoint method, the lightning hazard intensity was divided into grade I to IV, and the distribution map of lightning hazard intensity in Hubei province was drawn. Overall, the lightning hazard intensity in the whole province increased from northwest to southeast.

Key words: ground flash density, lightning current steepness, small current percentage, lightning hazard intensity, Hubei province
