The Science of Lightning – How Does a Strike Occur?
Colorado Lightning Safety Awareness Week continues through this Saturday. Today we discuss the science of lightning.
Every thunderstorm produces lightning. Lightning is simply a giant spark that moves within the cloud, between the clouds, or between the cloud and the ground. As lightning passes through the air, it heats the air rapidly to a temperature of about fifty thousand degrees Fahrenheit. This causes a rapid expansion of the air along the lightning channel. This rapid expansion causes a shock wave that we hear as thunder.
