Physics of Lightning :: lightning physics

Lightning can be defined as a transient, high menstruum galvanising discharge whose path length is generally measured in kilometers. Lightning occurs when some region of the atmosphere attains an electric charge sufficiently large that the electric fields associated with the charge cause electrical breakdown of the air. However lighting has been reported in snowstorms, sandstorms, in clouds over erupting volcanoes, and been reported to occur in the decipherable air. Such lightning can take place entirely within a cloud (intra cloud), between two clouds, between cloud and the earth, or between a cloud and the surrounding air. There really arent differrent types of lightning, almost all lightning discharges occur in basically the same way. However, varying conditio ns and situations that lightning occurs in make the flash appear
