地球的力量 第2集 大氣(15)難以琢磨

The problem is while the mountains make this areastormy,

問題是山上發(fā)生暴風(fēng)雨時(shí)

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

我們很難趕上

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

現(xiàn)在我看到的是陰沉的天空

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

烏云和塵土漫布天空

Look at that!

看!

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

閃電是空氣團(tuán)相互作用產(chǎn)生暴風(fēng)云

within the storm clouds.

時(shí)同時(shí)產(chǎn)生的

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

濕氣上升的時(shí)候冷卻，小水珠凝固

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

有一些變成了小的冰晶，有一些變成了大一點(diǎn)的冰塊

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

兩種不同的冰相互碰撞 產(chǎn)生了電

An electric field builds up until it becomes so strong

達(dá)到一定程度以后 產(chǎn)生了電場(chǎng)

it reaches for the Earth below.

接下來就會(huì)和地面接觸

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

不過雷電在大氣層中越高就越難以琢磨

much more exotic form of lightning

越壯觀

that's been caught on film.

這些被拍到底片上的

They're called sprites.

它們被稱為鬼神
