Then a strong current of electrons follows that path from the cloud to the ground, and it is that current that illuminates the channel as the lightning we see.

然后一股强大的电子电流沿着这条路径，从云层到达地面，正是这种电流像我们看到的闪电一样照亮了通道。

Storms producing cloud to ground lightning (lightning that strikes the ground) in isolated thunderstorms or super cells (which can be very dangerous) produce some dramatic pictures.

风暴产生的云团和雷电交加的暴风雨会产生地面闪电(击向地面的闪电)，或者超级闪电(可能非常危险)会拍出极具效果的照片。
