Then a strong current of electrons follows that path from the cloudto 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。

Using high-speed photography, scientists have determined that there are two steps to the occurrence of lightning from a cloudto the ground.
利用高速摄影技术,科学家们已经确定了闪电从云层到达地面有两个步骤。

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