Abstract: The paper aims to understand the occurrence law of lightning, and the mitigation of lightning disasters. Based on the cloud-to-ground lightning data in Heze during 2007-2013, the authors analyzed the spatio-temporal distribution characteristics of cloud-to-ground lightning. The results showed that: cloud-to-ground lightning in Heze was mainly affected by underlying surface and the spatial distribution was significantly different, lightning had a greater density near water; the moment distribution of cloud-to-ground lightning was multimodal, two of the largest peak appeared at around 5 am and 11 am; the lightning current intensity distribution of negative cloud-to-ground lightning matched the total flash well; the density of cloud-to-ground lightning and high values of high current density distribution were consistent, which was located in southern Dongming and northwestern Caoxian.
