From there, they use natural updrafts, also called mountain waves, to soar to the sky.

之后，飞机将利用上流飞翔，人们也把他叫作“地形波”。

The baby spiders felt the warm updraft.

蜘蛛娃娃们感觉到温上流。

Battling violent updrafts and acid clouds, these non-stick pioneers were swept nearly halfway round the planet.

对抗着上流和酸云, 些不为人知先驱者已经几乎环绕星一周。

The more condensation and the bigger the storm clouds grow, the more powerful those updrafts become.

凝结程度越大，并且形成风暴云团越大时，那些上流也就越强。

We're leaving here on the warm updraft.

“我们在乘着温上流离开里。

An updraft is also extremely treacherous because it can push an aircraft upward to dangerous altitudes.

上流也极其危险，因为它可以把飞机推到危险高度。

Spiraling updrafts lifted the sails, and the spiders were on their way.

螺旋上流扬起了帆，蜘蛛们正在赶来路上。

Tornadoes are thought to die off when thunderstorm updrafts lose energy.

当雷暴上流失去能量时， 龙卷风被认为会消失。

Did you make a solar updraft tower of your own?

您自己制作了太阳能上流塔吗？

We were caught in a strong updraft.

我们陷入了强烈上流中。

As that happens, an updraft is created when the warm air rises.

当种情况发生时， 当空上时会产生上流。

We're going to build something called a solar updraft tower.

我们要建造一个叫做太阳能上流塔东西。

What you're looking at is the peeled back artificial turf that was sucked up by the powerful updraft of this tornado.

你现在看到是被龙卷风强大上流吸走剥落人造草皮。

So, can you guess what our solar updraft tower will do?

那么，你能猜出我们太阳能上流塔会做什么吗？

There are some places in the world where they actually use giant solar updraft towers to generate electricity!

Once released from the surface, dust particles are raised to higher levels of the troposphere by turbulent mixing and convective updrafts.

一旦从地表释放出来， 尘埃粒就会通过湍流混合和对流上流上到对流层更高水平。

Hail is a form of precipitation consisting of solid ice that forms inside thunderstorm updrafts.

冰雹是一种降水形式， 由在雷暴上流中形成固体冰组成。

The conditions experienced by the hailstone can change as it passes horizontally across or near an updraft.

当冰雹水平穿过或靠近上流时， 冰雹所经历条件会发生变化。

This enhanced lift from the updraft increased the amplitude of the wave and made the  asperitas cloud here very visually impressive.
