Abstract:
|
This work presents an analysis of cloud-to-ground lightning strikes point patterns recorded during 2006-2010 by the National Lightning Detection Network (NLDN) over the state of Oklahoma. The physical and geographical characteristics that are studied include the total cloud-to-ground flash density, the positive flash density, the percentage of positive flashes, the first stroke negative and positive peak currents, and the multiplicity for negative and positive flashes. A univariate and bivariate point process analysis is performed, where the first refers to the total cloud-to-ground lightning point pattern and the second analyses the behavior between the positive and negative lightnings. The analysis of the first and second order properties is included.
