A lightning strikes over Lastur
A lightning strikes over Lastur during a summer storm August 1, 2004. Lightning originates around 15,000 to 25,000 feet above sea level when clouds become electrified by strong updrafts (fueled by the instability and moisture) bringing supercooled liquid water drops and ice crystals at temperatures less than freezing (0 deg C) together. In this environment, interactions between the ice crystals and supercooled water droplets produce electric charges. The electrical charges build up until they are strong enough to overcome the resistance of the surrounding air. The breakdown of the electric fields produced by these charges is the lightning bolt that normally reaches temperatures of 27.800 Celsius degrees (50,000° F).
