Study on lightning early warning information in the application of lightning risk assessment

In the lightning warning area, high lightning risk users were picked out based on lightning forecast products, considering rank of the client evaluated in previous work. When lightning early warning information was issued, probable variation of L_X (consequent loss in a structure) and h_z(factor increasing the loss when a special hazard is present) of different buildings were systematically studied. A Manufacture Plant was taken as an example, its R₁ (risk of loss of human life in a structure) was calculated in circumstance of different lightning protection measures. Rationalization proposals based on the result were put forward, which was meaningful for lightning risk assessment business.
