Now what about this shear thing?

那么什么是切呢？

Those storms want a lot of shear.

龙卷风非常需要风切。

There is a concern about something called wind shear.

有一种叫风切东西令人担忧。

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

晴空湍是由急风切产生。

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

龙卷风雷雨需要大量风切。风切指，风吹向不同方向，风速随高度而化。

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

风切，意味着暴风势力不会被分裂。

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

如果风切不大，雷暴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.

大气漂浮许多我们称之为 " 风切" 物体。

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

这就是温度、风切和湍之间联系。

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

当然，热带水是非常温暖，但是风切是什么？

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

但是气候暖也会影响到一些事情，比如风切位置和强度。

Wind going in different directions and different speeds with height.

风切是指，风向不同方向，在不同高度风速也不同。

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“风垂直切”东西，指是风速或风向随高度化。

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，即地球环切影响。

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

风切会导致形成水平旋转空气管。

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“快速增强”，需要几个条件，温度在86华氏度及以上水，没有风切。

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

710. 由于风切警告，我们复飞。

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

709. 我们收到“前方风切”警告。

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

我认为风切是飞行最危险天气。
