it gets whipped into huge hurricane-force winds.

This is a process we all have personal experience of.

这是一个我们都有切身体会的过程

When people go outside,

人们外出的时候

and one of the main reasons we feel cool

And by the same token

同样地

when water evaporates from the oceans

当水分从海洋中蒸发后

it takes heat out the oceans

把海洋的热量

and puts it into the atmosphere.

Hurricanes are so powerful

because the heat energy being transferred from the ocean to the atmosphere

The average hurricane turns that into
