Climate models and satellite observations both indicate that the total amount of water in the atmosphere will increase at a rate of 7% per kelvin of surface warming. However, the climate models predict that global precipitation will increase at a much slower rate of 1 to 3% per kelvin. A recent analysis of satellite observations does not support this prediction of a muted response of precipitation to global warming. Rather, the observations suggest that precipitation and total atmospheric water have increased at about the same rate over the past two decades.
气候模型和卫星观测都表明，大气中的总水量将随着地表每升温1开尔文而以7%的速率增加。然而，气候模型预测全球降水量的增速要慢得多，仅为每升温1开尔文增加1%至3%。最近一项对卫星观测数据的分析并不支持降水量对全球变暖反应不明显这一预测。相反，观测结果表明，在过去二十年里，降水量和大气总含水量的增加速率大致相同。
