This article shows the temporal behavior of lightning activity and its relationship with the meteorological variables involved in the formation of storms, in a mountain city. The results show that the lightning activity in Manizales has 69 thunderdays and that the months with most activity are March and November. The analysis was performed for both wet and dry periods. The results show that during the wet periods the activity of lightning is more intense and that it is mainly due to local winds and the displacement of the Intertropical Confluence Zone. The average diurnal cycle of meteorological variables is also presented, such as surface pressure, surface air temperature, dew point temperature, mixing ratio, zonal and southern winds.
