Analysis Of Lightning Activity In The South Of Hebei

To get correct lightning parameters based on lightning location system, a concept of statistical sampling database is presented, as well as the reasonable and acquisitive method for building the database is given after introducing and analyzing the great deal of detection data. The paper presents the grid method for statistic and analysis of some representative lightning parameters, such as thunderstorm day, flash density, 7, and so on, on the basis of the modern lightning detection data. However, the methods and conditions are compared with those in traditional meteorological data. A proper expression for cumulative probability distribution of cloud-ground flashes current amplitude is recommended. It is of very importance and significance to get a scientific, canonical statistical and analytical method, especially for study of comprehensive lightning parameters characteristic and its distribution rule.
