Mom! The dew point is 79.5 degrees. - Okay.

妈妈！露点是26.3摄氏度。 - 好的。

When the dew point drops in the middle of the night, it is perfect time for pythons.

当半夜露珠下降时，正是蟒蛇出没的最佳时机。

For instance, the air temperature, humidity and dew point will change significantly.

比如气温情况，还有湿度、露点。

The humidity is 90% with a dew point of 79.5 degrees.

湿度是90%，露点是26.3摄氏度。

The dew point is a lot more useful.

露点更有用。

So at the dew point, our metaphorical sponge would be full and a cloud can be born.

所以在露点，我们比喻的海绵 会充满，云会诞生。

And as this ejects out of the plane there's a little probe at the bottom that is going to collect all of our temperature, dew point, pressure, things like that.

当它喷射出飞机时，在底部有一个小探测器，它会收集所有的温度、露点、压力，诸如此类的参数。

Only when the air cools down past a certain point — called the dew point — does this breaking-apart slow down enough for little clusters of water molecules to grow into droplets.

只有在空气冷却到特定温度——即霜点温度——才能令断键过程减缓到可以让一小撮的水分子凝结成水滴。

And while there are millions of five-molecule clusters in a golf-ball-sized volume of air at dew point, odds are that only one of those clusters will grow to a size of ten.

在霜点温度下，一个高尔夫球体积大小的空气中存在无数由 5 个分子组成的水汽团，其中只有一个水汽团最终能聚到 10 个分子。

Clouds form when saturated air reaches  its dew point, the temperature at which, under a given set of barometric conditions, water  vapour condenses into liquid due to cooling air or increased saturation from an adjacent water  source.

当饱和空气达到露点时， 云就会形成。露点是在给定的气压条件下，水蒸气由于冷却空气或邻近水源饱和度增加而凝结成液体的温度。
