湖泊的生态和地球化学过程强烈地依赖于水温。许多湖泊的长期表面变暖是明确的，但由于缺乏适当解决的数据，人们对昼夜时间尺度的温度变化的相对幅度知之甚少。在这里，我们量化的模式和幅度的昼夜温度变化的表面沃茨使用高频数据从100个湖泊。我们发现，近地表昼夜温度范围可以是相当大的，在夏季相对于长期的变化，对于小于3平方公里的湖泊，急剧增加，并可预测的减少湖泊面积。本研究中包括的大多数小型湖泊的近地表温度在4至7°C之间，平均夏季昼夜变化范围。大部分湖泊的昼夜温度波动无疑会影响它们的结构、功能和在地球化学循环中的作用，但其全部影响在很大程度上仍未得到探索。
Ecological and biogeochemical processes in lakes are strongly dependent upon water temperature. Long-term surface warming of many lakes is unequivocal, but little is known about the comparative magnitude of temperature variation at diel timescales, due to a lack of appropriately resolved data. Here we quantify the pattern and magnitude of diel temperature variability of surface waters using high-frequency data from 100 lakes. We show that the near-surface diel temperature range can be substantial in summer relative to long-term change and, for lakes smaller than 3 km2, increases sharply and predictably with decreasing lake area. Most small lakes included in this study experience average summer diel ranges in their near-surface temperatures of between 4 and 7°C. Large diel temperature fluctuations in the majority of lakes undoubtedly influence their structure, function and role in biogeochemical cycles, but the full implications remain largely unexplored.
