Why Lightning Never Leaves This One Lake
About this video
Over Lake Maracaibo in Venezuela a thunderstorm switches on most nights of the year, runs for seven to ten hours, throws lightning at up to 28 flashes a minute, and shuts down before dawn. Sixteen years of satellite data rank it first on Earth for flash density — about 232 flashes per square kilometre per year. Sailors once navigated by its glow. The explanation almost everyone repeats is wrong. Methane from the basin's oil deposits and swamp gas is not present in concentrations that could change how a thunderstorm builds charge, and the flashes cluster over open water rather than over the seeps. The uranium version has no anomalous uranium to stand on. What actually drives it is ordinary convection, assembled more reliably here than anywhere else: a basin walled in on three sides, water that stays warm overnight, cold air sliding down every slope after sunset and converging over the middle, and tropical air humid enough to build very tall cloud. The honest gap is that describing the ingredients is manageable and reproducing the intensity is not — and when the 2010 drought shut the storm off for six weeks, it showed how tightly the whole thing is bound to the state of the water.
