evaporation

Water enters air via evaporation.

水通过蒸发进入空气。

Because it is located in a very hot and dry region, the Dead Sea loses much water through evaporation, causing its level to fluctuate during the year.

因为它处于一个非常炎热和干燥的地区，死海由于蒸发损失掉大量的水，导致其水平面一年到头不断波动。

There has not been much change in rainfall in those areas but the temperature has risen by over 1 degree Centigrade since 1970, which will have enhanced losses due to evaporation.

那些地区的降雨量没有太大变化，但是自1970年以来上升的气温已经超过了1摄氏度，由于蒸发这将会造成水分的更大流失。
