ABSTRACT:
An apparatus and method for warning against lightning strikes, in which the rate of occurrence of ground flashes is determined and used as a criterion. The rate of occurrence of ground flashes in 0 to 5 kilometers, 5 to 10 kilometers and 10 to 20 kilometers is determined. In addition, the field intensity is used as a criterion. A series of time windows is generated, each time window starting when a ground flash occurs, and the number of flashes occurring in each time window is counted to determine the rate of occurrence. A criterion selection matrix is provided to select various criteria in different combinations to provide different alarm levels.
