Discussion Overview
The discussion centers around the inquiry into the most powerful and energetic lightning bolts, specifically "superbolts," and seeks referenced data on their maximum possible energy discharge. Participants are interested in both direct measurements and indirect estimates, such as those derived from satellite observations.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant requests properly referenced data about the energy of superbolts, emphasizing the need for measurements in joules rather than power in watts.
- Another participant points out that many reports incorrectly refer to power without considering discharge time, highlighting a specific case where a lightning stroke exceeded 3 terawatts of power.
- There is a consensus among participants that the information found is inadequate without discharge time, volts, or amps to calculate energy in joules.
- A reference to the EU standard for lightning protection is made, which quotes a figure of 10 MJ/Ohm for energy delivered in worst-case flashes.
Areas of Agreement / Disagreement
Participants generally agree on the inadequacy of available information regarding the energy of superbolts and the importance of having measurements in joules. However, there is no consensus on specific data sources or the interpretation of existing data.
Contextual Notes
Participants express limitations in the available literature, particularly regarding the lack of discharge time and the need for clear definitions of energy measurements.
