The relationship between topographic information data (land cover type, elevation, aspect and slope) and the parameters such as the frequency of CG (Cloud-to-Ground) lightning, the positive ratio of CG lightning, lightning return stroke intensity and lightning return stroke steepness is quantitatively studied based on the CG lightning data from 2007 to 2019, land cover type data and the digital elevation model data. The results show that CG lightning frequency per unit area and the proportion of small-amplitude CG lightning in the built-up area are relatively high, which are 87.1 times/km² and 8.6%, respectively. The CG lightning return stroke steepness in cultivated areas and water areas is higher than those in other land cover types. The return stroke of CG lightning in Hubei Province is mainly concentrated at an altitude of 0 to 700m and a slope interval of 0.5° to 35°. The return stroke density of CG lightning generally decreases with the altitude increase. The average return stroke intensity of CG lightning first increases and then decreases with altitude increase. The average return stroke steepness of CG lightning decreases with the altitude increase. The CG lightning return stroke density is higher in the south or east of the slope. CG lightning’s average return stroke intensity is higher in the south or north of the slope. The lightning parameter changes in different slope and altitude intervals are relatively consistent.
