Paper Title
Probability Of Cloud-To-Ground Lightning Strikes

Abstract
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. Keywords - Collective Area, Cloud To Ground Lightning, Probability Of Strike, Striking Distance.
