蒸发量(evaporation),水由液态或固态转变成气态,逸入大气中的过程称为蒸发。而蒸发量是指在一定时段内,水分经蒸发而散布到空中的量。通常用蒸发掉的水层厚度的毫米数表示,水面或土壤的水分蒸发量,分别用不同的蒸发器测定。一般温度越高、湿度越小、风速越大、气压越低、则蒸发量就越大;反之蒸发量就越小。土壤蒸发量和水面蒸发量的测定,在农业生产和水文工作上非常重要。雨量稀少、地下水源及流入径流水量不多的地区,如蒸发量很大,即易发生干旱。

水持续蒸发,冷凝,沉降。 在全球范围看来,蒸发量约等于沉降量。
Water continually evaporates, condenses, and precipitates, and on a global basis, evaporation approximately equals precipitation.
雨水被导入沙砾储水区,这样有两个好处,一是能够过滤雨水,二是能够减少水的蒸发量。
Rainwater is channelled into sand catchments, which serve both to filter it and to protect it from evaporation.
趋势是一样的:海洋的蒸发量增加导致陆地上降水增加和流入大海中的水量增加。
The trends were all the same: increased evaporation from the ocean that led to increased precipitation on land and more flow back into the ocean.
