We're not sure. We know that areas having a high electric potential as compared to the ground evolve under the right conditions. Eventually the potential is high enough for a discharge to occur [I think about 30KV per meter], but the mechanism of charge separaton is not understood - at least there is no explanation that is universally accepted as being definitive.

Okay, My question is related to this topic so I will ask it here rather than creating a new topic.

I want to know the temperature attained by the air around a
space(at normal temperature and pressure) where a corona discharge takes place.
Also can the process of corona discharge be taken as an adiabatic process?

Thanks in advance for the replies.
