Lightning occurs when clouds having opposite charges come close together. When the electrostatic potential of either of them exceeds the breakdown voltage of air, electrons start flowing between them causing a lightning current.
Lightning is not strictly categorized as either AC or DC in the conventional sense due to its transient nature. Lightning can be considered as an impulse of high voltage and high current electricity.
There is a contradiction between the scholars to define the nature of this current. Since it goes in one direction only and it does not repeat in alternating cycles hence it may be defined as DC but it has a positive and negative signal with DC offset and also has some frequency content which defines it as AC.
In summary, while lightning does not confirm strictly to the definition of AC or DC, it is better understood as a transient, high-energy electrical discharge that exhibits characteristics of both types of current flow.
