Helicopter-triggered lightning strike

Helicopter-triggered lightning strikes is when a "helicopter itself [... is a main reason for a] lightning strike [... or hit. Other reasons] are needed to create the right conditions for helicopter"-"triggered lightning, which has been observed in [... the] North Sea [... and] sea near Japan".^[1]

These lightning strikes happen especially^[2] when there is snow fall and the temperature is around 0 degrees celsius.

The phenomenon has been studied for several years (as of 2015).^[1]
