Actual air temperature is combined with relative humidity to measure what?

实际空气温度和相对湿度结合起来测量什么？

The ease with which water can be won from air depends on that air's relative humidity.

从空气中获取水分难易程度取决于空气相对湿度。

They're going to tell you temperature, relative humidity, wind speed and direction, as well as pressure.

它们会告诉你温度、相对湿度、风速、风向和大气压。

A relative humidity of 100% means the air in question is holding as much water vapour as it possibly can.

100%相对湿度意味着空气中含有可能多水蒸气。

In the hottest room it boosted the relative humidity of inspired air by over 50%, compared with breathing without a mask.

热房间里，戴棉质口罩呼吸与不戴口罩呼吸相比，它使吸入空气相对湿度提高了50%以上。

But in these conditions, when relative humidity is near 100%.

但这些条件下，当相对湿度接近 100% 时。

Relative humidity is the amount of moisture that the air can hold.

相对湿度是空气可以容纳水分含量。

So you might have two days where the relative humidity is 50%.

所以你可能有两天相对湿度是 50%。

132. The relative humidity is the amount of moisture that the air can hold.

相对湿度是空气中所能容纳湿气量。

The vapor-pressure deficit indexes two other measurements: the air temperature and the relative humidity.

蒸气压不足指示另外两个测量值：空气温度和相对湿度。

But yeah, that's… and actually, I don't even know what relative humidity is, so maybe it's just humidity.

但是，是，那是… … 实际上，我什至不知道相对湿度是什么，所以也许只是湿度。

So even though people talk about it a lot, the relative humidity forecast isn’t a great way to tell how hot it feels.

因此，管人们经常谈论它，但相对湿度预报并不是判断感觉有多热好方法。

A good way to get air to give up some of its moisture is therefore to cool it to the point where its relative humidity exceeds 100%.

因此，让空气失去一部分水分一个好办法是将其冷却到相对湿度超过100%程度。

Even if relative humidity stayed the same at 50 percent—that is, even if average humidity rose to 53.7 units of humidity—the VPD would still rise.

即使相对湿度保持 50% 不变——也就是说， 即使平均湿度上升到 53. 7 个湿度单位——VPD 仍会上升。

With the highest now fully installed, the eight stations will work together to record temperatures, relative humidity, wind speeds, wind direction, solar radiation and other data on the northern slope of Mount Qomolangma.

高气象站现已全部安装完毕，八个气象站将协同工作，记录珠穆朗玛峰北坡温度、相对湿度、风速、风向、太阳辐射和其他数据。
