Most visually effective lightnings occur over city skylines, somehow. That must be due to the added element of danger; they might strike a building or wreak havoc on the city's energy grid.
Various skylines featured here belong to Toronto, Sydney, Hong Kong, Singapore; other backdrops to heavenly unrest include the Arizona desert, Bryce Canyon, Baltic Sea, Madeira island or a nameless field in Wilmington, North Carolina. In every case, the display of electrical storm lights is both humbling and exhilarating.
