Probability Of Cloud-To-Ground Lightning Strikes
Lightning is a massive electrostatic discharge caused by the circulation of warm moisture-filled air through an
unbalanced electric field in the atmosphere, accompanied by the loud sound of thunder. Lightning strikes 40–50 times a
second worldwide, for a total of nearly 1.4 billion flashes per year. Lightning is not distributed evenly around the planet.
About 70% of lightning occurs on land in the tropics, where most thunderstorms occur. The technology of lightning
protection have registered steady improvements but even with all the known precautions, complete safety is still beyond our
reach. Still hundreds of deaths occur in each year from lightning stroke. There are incidents which are not reported too. The
damages are huge and often not reported. It is generally believed that lightning strikes only the tallest objects The authors
have visited various places of lightning strikes for the past few years and in this paper, a typical case of lightning strike is
discussed, where lightning had struck a neem tree surrounded by tall trees, buildings and a tower.
