With the paper “Cloud-to-Ground Lightning activity in Colombia and the influence of topography”, available* on line since 31 August 2016, results of our working team continue contributing to the lightning understanding.

Lightning activity on the Colombian mountains, where the altitude varies from 0 to more than 5,000 MSL, is studied based on VLF/LF lightning detection data and using a 2012-2013 dataset. The influence of altitude is observed by evaluating cloud-to-ground lightning incidence at different altitude intervals. The relationship between ground Flash density and altitude gradient vectors is studied. Results show a clear dependence of the Flash density on elevation.
