Now what about this shear thing?

那么什么切呢？

Those storms want a lot of shear.

龙卷非常需要切。

There is a concern about something called wind shear.

有一种叫切的东西令人担忧。

Clear air turbulence is generated by wind shear in the jet stream.

晴空由急中的切产生的。

Those storms want a lot of shear. Wind going in different directions and different speeds with height.

龙卷雷雨需要大量的切。切指，吹向不同的方向，速随高度而化。

Less shear down here means the storms aren't going to be torn apart.

切减小，意味势力不会被分裂。

And if there isn't much of that, the thunderstorms can build more straight upward.

如果切不大，雷就能一路向上逐渐增强。

Heavy rain and flooding triggered by the shear line have been seen in many regions in the country.

菲律宾多地受切线影响造成大雨和洪水。

A lot of what we call shear in the atmosphere.

大气中漂浮许多我们称之为 " 切" 的物体。

So that's the link from temperatures to winds shear to turbulence.

这就温度、切和之间的联系。

And so of course, the water down in the tropics is very warm, but what about this shear thing?

当然，热带的水非常温暖的，但切什么？

But these warmer conditions also affect things like where's the wind shear and how strong is it?

但气候暖也会影响到一些事情，比如切的位置和强度。

Wind going in different directions and different speeds with height.

切指，向不同的方向，在不同的高度速也不同。

And there's something called vertical wind shear, which is a change in wind speed or direction with height.

还有一种叫做“垂直切”的东西，指的速或向随高度的化。

This usually happens away from the intense effects of the jet streams – strong wind paths that circle the planet.

通常发生在远离高空急，即地球环的切影响。

And that wind shear can cause a horizontal rotating tube of air to form.

切会导致形成水平旋转的空气管。

For true RI, or rapid intensification, you need a couple things, 86 degrees Fahrenheit water or greater and no shear.

想要实现真正的“快速增强”，需要几个条件，温度在86华氏度及以上的水，没有切。

710. We made the go around due to wind-shear warning.

710. 由于切警告，我们复飞。

709. We have a " Wind-shear Ahead" warning.

709. 我们收到“前方切”警告。

I think wind shear is the most dangerous weather to fly in.

我认为切飞行中最危险的天气。
