The map on the right shows that lightning is not distributed evenly around the planet. About 70% of lightning occurs on land in the Tropics, where the majority of thunderstorms occur. The north and south poles and the areas over the oceans have the fewest lightning strikes.
The earth experiences about 44,000 thunderstorms every day, with approximately 1,800 storms in action at any given moment. The most active area in the world is Java, an island of Indonesia, with an average of 223 storm days per year. Florida is known as the lightning capital of the United States, with storms occurring approximately 100 days out of the year, compared to California's low of only 5.
