地球的力量 第2集 大气(15)难以琢磨

The problem is while the mountains make this areastormy,

问题是山上发生暴风雨时

they don't make it easy to catch up with the storm.

我们很难赶上

Right now, all I see is a black sky in front of me.

现在我看到的是阴沉的天空

It's just a wall of dark cloud and dust.

乌云和尘土漫布天空

Look at that!

看!

The lightning is just the by-product of the extreme air movements

闪电是空气团相互作用产生暴风云

within the storm clouds.

时同时产生的

As the moist air rises, it cools and water particles freeze.

湿气上升的时候冷却，小水珠凝固

Some become small ice crystals, others larger, slushy ice.

有一些变成了小的冰晶，有一些变成了大一点的冰块

These two different types of ice collide and become electrically charged.

两种不同的冰相互碰撞 产生了电

An electric field builds up until it becomes so strong

达到一定程度以后 产生了电场

it reaches for the Earth below.

接下来就会和地面接触

But far higher in the atmosphere is a much more elusive,

不过雷电在大气层中越高就越难以琢磨

much more exotic form of lightning

越壮观

that's been caught on film.

这些被拍到底片上的

They're called sprites.

它们被称为鬼神
