What are the most energetic lightning "superbolts" ever measured?

In summary, the conversation discusses the need for properly referenced data on the most powerful and energetic lightning bolts on Earth, with a focus on their total energy discharge in joules. The speaker mentions searching for papers on "superbolts" but finding nothing useful, and also notes the confusion surrounding the reporting of power in watts rather than discharge time. They also provide a link to an article about a lightning strike that exceeded 3 terawatts of power. The conversation ends with a reference to the EU standard for lightning protection, which quotes a figure of 10 MJ/Ohm for the energy delivered in 10% worst case flashes.

TL;DR Summary
Highest known energy of lightning on Earth, directly measured or estimated by other means like e.g. satellite observation.
Hi! I would be interested in properly referenced data about the most powerful / energetic lightning bolts on Earth to get a good idea about their maximum possible order of magnitude (maybe depending on location?) Both direct measurements or indirect but well-founded estimates (e.g. satellite observations) are OK. Can you help me, please?

Have you searched for papers about superbolts ?

For a single strike event the specification should be the total energy discharge in joules.
It seems many reporters wrongly refer to power in watts, but not the discharge time.

Yes I have, and I didn't find anything useful. That's why I came to ask.

Indeed.

Yep, that's the kind of info I found ---useless without the discharge time. Also in volts, in amps... but never in joules or anything that let me calculate the joules. :frown:

I notice that the EU standard for lightning protection, EN-62305 page 35, quotes a figure of 10 MJ/Ohm for the energy delivered in 10% worst case flashes.

What are the most energetic lightning "superbolts" ever measured?

The most energetic lightning "superbolts" ever measured are extremely rare and powerful lightning strikes that release over 100 times more energy than a typical lightning bolt.

How are "superbolts" different from regular lightning bolts?

"Superbolts" are different from regular lightning bolts in their intensity and energy release. They can be up to 100 times more powerful and can travel much farther than a typical lightning bolt.

How are "superbolts" measured and recorded?

Scientists use specialized instruments called lightning mapping arrays to measure and record "superbolts". These arrays can capture the entire lightning event, including the initial breakdown, the main lightning stroke, and the continuing current.

What causes "superbolts" to occur?

The exact cause of "superbolts" is still unknown, but scientists believe that they are the result of a combination of factors including strong upward currents in thunderstorms, a high concentration of electric charge, and favorable atmospheric conditions.

Can "superbolts" be predicted?

Currently, "superbolts" cannot be predicted with any level of accuracy. However, scientists are working to better understand the conditions that lead to their occurrence in hopes of eventually being able to predict them.
