This is a great example of a staccato cloud to ground lightning strike (in this case cloud to sea). Staccato cloud-to-ground lightning is perhaps the most photogenic of all lightning. It is termed “staccato” because the lightning is comprised of just one single, rapid discharge and is typically accompanied by a myriad of interesting and intricate branching.
I caught this one at 5am just off the Warrnambool coast a couple of weeks ago – very nice !
