二战后美国和前苏联大部分地区观测到的蒸发皿蒸发量减少，如果解释为实际蒸发量减少，则与这两个国家许多地区的温度和降水增加不一致。通过对6个俄罗斯、1个拉脱维亚和1个美国试验点的实际蒸发量和蒸发量的平行观测，我们重新校准了蒸发量的趋势，使其更能代表实际蒸发量的变化。应用这一转换后，俄罗斯南部和美国大部分地区的蒸发皿蒸发量时间序列在过去40年中显示出实际蒸发量增加的趋势。
Observed decreases in pan evaporation over most of the United States and the former USSR during the post‐WWII period, if interpreted as a decrease in actual evaporation, are at odds with increases in temperature and precipitation over many regions of these two countries. Using parallel observations of actual and pan evaporation at six Russian, one Latvian, and one U.S. experimental sites, we recalibrate trends in pan evaporation to make them more representative of actual evaporation changes. After applying this transformation, pan evaporation time series over southern Russia and most of the United States reveal an increasing trend in actual evaporation during the past forty years.
