北美五大湖附近降水和河流径流的同位素组成的特点是比平流气团中观测到的氘过量值更高。有人认为，这表明地表水蒸发的水分与大气水混合在一起。对夏季和秋季大气水分平衡的初步估计表明，大湖区顺风方向大气含水量的4.6%-15.7%来自夏季的湖泊蒸发。
The isotopic composition of precipitation and river runoff in the vicinity of the North American Great Lakes is characterized by a higher deuterium-excess value than observed in the advecting air masses. It is suggested that this indicates that evaporated moisture from the surface waters is mixed with the atmosphere waters. A preliminary estimate of the atmospheric water balance during summer and autumn indicates that between 4.6%-15.7% of the atmospheric water content downwind from the Great Lakes is derived from lake evaporation during summer.
