In ancient Rome, it was believed that thunderstorms were caused by the god Jupiter, who created lightning by hurling great bolts forged by Vulcan. The Norse believed that Thor's crashing hammer created sparks that rained upon the earth as lightning. Some Native Americans believed that thunderstorms were caused by the coming of powerful birds, servants of the Great Spirit.
Though we have different ideas about the formation and behavior of storms today, we are no less captivated by their drama. Indeed, scientists and amateur photographers alike still train their instruments and lenses on these powerful forces of nature.
What they have found is that, like many other natural systems, human's are changing the behavior of storms.
