There's been a quite a bit of wind shear in the upper atmosphere, hurricanes don't like wind shears.

在高层大气中存在相当多的乱流, 而飓风偏不喜欢乱流。

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

晴空湍流是由急流中的风切变产生的。

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

这就是温度、风切变和湍流之间的联系。

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

但是气候变暖也会影响到一些事情，比如风切变的位置和强度。

Here in Mumbai, fierce winds sheared off part of the NPR bureau's roof. Lighter winds and rain continue.

在孟买，狂风刮掉了NPR分社的部分屋顶。风力和雨势渐缓，但仍在持续。

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“风垂直切变”的东西，指的是风速或风向随高度的变化。

Pilots use it to help with landing planes and identifying dangerous changes in wind speed and direction known as wind shear.

飞行员使用它来帮助飞机着陆，并识别风速和方向的危险变化，即风切变。

When the wind shear is too strong, the atmosphere simply can't contain that and it breaks down into turbulence as a result.

当风切变太强时，大气根本无法容纳它，结果它就分解成湍流。

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

风切变会导致形成水平旋转的空气管。

Officials say it is too early to say what caused the crash, but investigators are expected to look into wind shear as a possibility.

有关官员说，现在断言飞机坠毁原因为时过早，但预计调查人员将调查“风切变”的可能性。

A low wind shear allows the storm to develop vertically, which is crucial for the formation of a hurricane.

低风切变允许风暴垂直发展，这对于飓风的形成至关重要。

Once the storm formed, exceptionally strong wind shear appears to have prevented the tornadoes from dissipating, experts say.

专家说，一旦风暴形成， 异常强烈的风切变似乎阻止了龙卷风消散。

Changes in wind speed and direction with height, also known as wind shear, can either encourage or inhibit hurricane development.

风速和风向随高度的变化，也称为风切变，可以鼓励或抑制飓风的发展。

When winds vary in speed or direction at different altitudes – a condition known as wind shear – the updraft will start to spin.

当风在不同高度的速度或方向发生变化时——这种情况称为风切变——上升气流将开始旋转。

Now, together, this helped to create wind shear, down near the perimeter, and that is what helps create some of the more violent tornadoes.

现在，这有助于在周边附近产生风切变，这有助于产生一些更猛烈的龙卷风。

Now, together, these help to create wind shear, down near the perimeter and that is what helps create some of the more violent tornadoes.

现在，这些一起有助于在周边附近产生风切变，这有助于产生一些更猛烈的龙卷风。

We`ll have decrease in wind shear and it could be just that perfect environment to get some of the storms going in the Atlantic.

我们将减少风切变，这可能正是让一些风暴进入大西洋的完美环境。

NOAA expects sea surface temperatures to be average or above average, and it doesn't expect a lot of vertical wind shear which can weaken hurricanes.

NOAA 预计海面温度将处于平均水平或高于平均水平，并且预计不会有很多可以削弱飓风的垂直风切变。

However, there could be other reasons, such as  horizontal wind shear; convection, which is the exchange of matter or temperature between fluid  bodies; or atmospheric gravity waves.

然而，可能还有其他原因， 例如水平风切变；对流，即流体之间的物质或温度交换；或大气重力波。

Clear-air turbulence, or CAT, as I like to call it, is caused by wind shear, which is what happens when wind meets other wind moving at a super different speed or direction.

晴空湍流， 我喜欢称之为 CAT，是由风切变引起的， 当风遇到以极不同的速度或方向移动的其他风时就会发生这种情况。
