Lightning storms could be every dangerous or it could bring excitement and joy to people''s eyes. Lightning is an electrical discharge caused by an imbalance between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. "Sheet lightning" describes a distant bolt that lights up an entire cloud base. Other visible bolts may appear as bead, ribbon, or rocket lightning. Today, in my area, there was a weak thunderstorm that only remained for 30 minutes. I personally think that lightning storms are very interesting and could be an topic, that anybody can talk about.
