Embodiment Construction

[0013] In the following, the embodiments of the present invention will be further described in detail in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the present invention enters the original lightning record data of the artificial weather station (that is, the original lightning data of the artificial weather station) and the automatic monitoring data of the lightning location system through a computer, and uses a computer to process the data. Using a computer program with GIS function, the original lightning record data of the artificial weather station and the automatic monitoring data of the lightning positioning system are used as statistical samples, which are input into the computer respectively, and based on the digital map, the original lightning record data of the artificial weather station are collected Processing with the automatic and manual monitoring data of the lightning positioning system, establishing a statistical data syst...

Abstract

This invention discloses a thunder parameter confirm method which includes the following characteristics: it adopts computer to deal with the raw material and data from the station; a database was established based on GIS to divide the area to different grid and conduct statistic on the data from each grid and make every grid have coordinate system geographic attribute same with that of thunder automatic monitoring data and artificial weather station thunder original data; the region of grid relative to the thunder parameter is counted. The advantages are as follows: it can be applied to large area material, large sample and auto-monitored data; the operation is simple and practicable.

Description

technical field [0001] The invention relates to a statistical method for lightning parameters, in particular to a statistical method for determining lightning parameters by using a grid method. Background technique [0002] Lightning parameters (such as lightning day, ground flash density, etc.) are used to represent the characteristics of lightning activity in a certain area, and are an important basic data in lightning protection engineering design or checking calculation. In the past, due to the lack of automatic monitoring methods for lightning, the source of statistical data of lightning parameters was based on the manual monitoring records of conventional ground meteorological observation stations. As far as the applicant knows, according to the provisions of the Meteorological Organization: if a certain weather station manually records an audible lightning sound on a certain day, it is a thunder and lightning day in the area represented by the weather station, which i...
