From what I remember, water changes back and forth from water in lakes and oceans to vapor, and then back to water again when it falls as rain or snow, as precipitation.

根据我的记忆，水往复地变化，从湖泊和海洋里的水变成水蒸气，然后当它以雨或雪——也就是降水的形式落下时又变成水。

With temperatures rising and more water vapor in the air, such storms can pull in more moisture and thus rain or snow more heavily than storms of old.

随着气温升高，空气中的水蒸气增多，这样的风暴会吸收更多的湿气，因此雨雪会比以前的风暴来得更猛烈。

After being absorbed, the particles of water unite and form clouds; then they fall down in the form of fog, rain, snow, or hail.

原来，水分被空气吸收以后，空气中的水分子就会积聚成云，然后它们会变成雨，变成雪，变成冰雹降落下来。
