I understand corona discharge in electrostatic situations, but in circuits without capacitors/gaps, I don't understand why it can ever happen (since as far as I know, the electric field is virtually 0 in the air around such a circuit). So why is there corona discharge around high-voltage power lines when there are more charged particles in the surrounding air than normal (like after a nearby lightning strike)? There's something I'm missing here and I have no idea what it is.
