由于湖泊水位是由蒸发率和降水量控制的，对这种水位的解释是模糊不清的。
Since lake levels are controlled by rates of evaporation as well as by precipitation, the interpretation of such levels is ambiguous.
对于超高温火灾增多的一种解释是，该地区夏季通常很干燥，近年来降水量明显低于正常水平。
One explanation for the trend to more superhot fires is that the region, which usually has dry summers, has had significantly below normal precipitation in many recent years.
要么基于他自己本能的喊叫，像是看到降水时惊奇地吞咽口水的声音，或是把岩石敲进头骨，使劲叫喊的声音。
Or on his own instinctive cries, like a gulp of surprise at the sight of falling water or a yelp of effort caused by smashing a rock into a skull.
降水往往会把细小的粘土颗粒转移到土壤的最微小的空隙中，使这些空隙变得封闭，从而形成了一种几乎不允许任何水分渗透下来的表层土壤。
The impact of raindrops on the loose soil tends to transfer fine clay particles into the tiniest soil spaces, sealing them and producing a surface that allows very little water penetration.
