water droplets in clouds的意思|示意

Fact: clouds, which consist of water droplets and ice crystals, seem to hover in the air.

事实：云，由小水滴，冰晶，好像在空中盘旋。

Eventually, water vapor in the cooled air condenses into the droplets that form clouds.

最终，水蒸气凝结成水滴空气冷却而形成的云。

Like all clouds, it forms when the air reaches its dew point, which is the temperature to which an air mass must be cooled for the water vapor in it to condense into liquid droplets.

和其他云一样，它是当空气达到凝结点，即空气团的温度冷却到使其中的水蒸气凝结成液态水滴的温度时形成的。

These occur in cirrus or cirrostratus clouds, which are often composed of ice crystals and super-cooled water droplets - water that is below freezing temperature, but still in liquid form.

这些云层发生在卷云或卷层云，它们通常包含着冰晶和过冷的水滴——温度低于冻结温度却依然能保持着其液体的状态。

The water droplets in the clouds quickly become larger and heaver.

云中的水滴很快地变得越来越大，越来越沉。

Clouds are formed from the evaporation of the oceans' water that is warmed by the Sun and rises high into the atmosphere, condensing in tiny droplets on minute particles of dust.

云是由海洋中的水分被太阳加热蒸发而形成的，这些水分上升到大气中，凝结成微小的水滴，附着于微小的尘埃颗粒。
