Massive Lightning storm over the city lights. North Scottsdale, Arizona. This is a layered shot that would equal to about a 10 minute exposure. Fact: A moving thunderstorm also gathers positively charged particles along the ground that travel with the storm. As the differences in charges continue to increase, positively charged particles rise up tall objects such as trees, houses, and telephone poles—and people. The negatively charged bottom part of the storm sends out an invisible charge toward the ground. When the charge gets close to the ground, it is attracted by all the positively charged objects, and a channel develops. The subsequent electrical transfer in the channel is lightning.
