"The Catatumbo Lightning in Venezuela is the world's largest single generator of ozone. It is a cloud storm that forms a voltaic arc at more than 5 km of height, during 140 to 160 nights a year, 10 hours per day and up to 280 times per hour, over the bog area that forms where the Catatumbo River flows into the Lake Maracaibo.
The collision with the winds coming from the Andes Mountains causes the storms and associated lightning, a result of electrical discharges through ionised gases, specifically the methane created by the decomposition of organic matter in the marshes. Being lighter than air, the gas rises up to the clouds, feeding the storms."
