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

之后，飞机将利用上升气流飞翔，人们也把他叫作“地形波”。

This heats the surrounding pocket of air, giving it lift and sucking more moist air up behind it, which cools and condenses and releases heat, which fuels lift and strengthens the updraft.

这加了周遭空气，让它上升并吸起更多下方湿空气，湿空气凝结又释放，续驱动并强化上升气流。

For instance, stratus clouds-those unlovable, featureless sprawls that give us our overcast skies, happen when moisture-bearing updrafts lack the oomph to break through a level of more stable air above, and instead spread out, like smoke hitting a ceiling.

比如，要是携带水汽上升气流无法突破上面比较稳定一层空气，就会像烟碰到了天花板那样向外展开，于是就形成了层云一那种不大讨人喜欢，毫无特色，弄得天空阴沉沉云层。

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升气流吸走剥落人造草皮。

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，那些上升气流也就越强。

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

对抗着上升气流和酸云, 这些不为人驱者已经几乎环绕这颗行星一周。

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

上升气流也极其危险，因为它可以把飞机推到危险高度。

We're leaving here on the warm updraft.

“我们在乘着这温暖上升气流离开这里。

Pilots don't see updrafts on their radars at night, and when a plane hits one, it feels like driving over a huge speed bump at 500 miles per hour.

飞行员晚上在雷达上看不到上升气流，当飞机碰到上升气流时，感觉就像以每小时 500 英里速度驶过一个巨大减速带。

And if the supply of water vapor is much larger, the energy released can produce stratosphere-high pillars of cloud with violent updrafts, fierce electrical storms, and grapefruit-sized hailstones.

如果水蒸气供给足够多，所释放能就可以形成平流层高度云柱，伴随着猛烈上升气流，造成猛烈雷暴，下起葡萄柚大小冰雹。

The most extreme white-knuckle turbulence is super rare, but an updraft is a big air mass — part of a storm or some other weather phenomenon moving upwards.

最令人恐惧极端乱流非常罕见，但上升气流是一种巨大气团——风暴或其他天气现象一部分向上移动。

AND THE GULLS, PLAYING IN THE UPDRAFTS. IN IRELAND, YOU DRIVE ON THE LEFT.

和海鸥， 在上升气流中嬉戏。 在爱尔兰， 您靠左行驶。

" Updraft" just means a kind of wind where air moves up.

“上升气流”只是指一种空气向上移动风。

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

冰雹是一种由固体冰组成降水形式， 在雷暴上升气流中形成。

It takes experience and skill to weave in and out of the fire's hot updrafts.

穿梭于火上升气流中需要经验和技巧。

Paul looked down, saw the dust-defined pillar of hot wind that had disgorged them, saw the dying storm trailing away like a dry river into the desert-moon-gray motion growing smaller and smaller below as they rode the updraft.

保罗低头看去，看到了吐出他们风尘埃柱，看到垂死风暴像一条干涸河流拖入沙漠月灰色运动中，随着他们乘着上升气流在下面变得越来越小。

Crane then says, quote, B-29 crews fought superheated updrafts that destroyed at least 10 aircraft and wore oxygen masks to avoid vomiting from the stench of burning flesh.

克兰接着说，引述道，B-29轰炸机机组人员遭遇了高温上升气流，这摧毁了至少10架飞机，他们还佩戴氧气面罩以避免因烧焦肉体恶臭而呕吐。

Around ground zero, a fierce updraft sweeps  hot, vaporized debris into the atmosphere, forming a mushroom-shaped cloud taller than any  structure on Earth.

在零地周围，猛烈上升气流将炽汽化碎片扫入大气中，形成比地球上任何结构都高蘑菇状云。

Like the thermal updrafts that hawks and vultures ride on, finding even the smallest patches of turbulence in the air to carry them.

就像鹰和秃鹫利用气流一样，它们甚至能发现空气中最小湍流来让自己飞翔。
