| 英文摘要 | Lake heat storage is essential in regulating lake evaporation's magnitude and seasonal variation. However, its impacts on lake evaporation are inadequately investigated, mainly due to the limited lake-water-temperature- profile observations used to calculate lake heat storage, challenging the accurate quantification of lake evaporation. Hence, we integrate multiple-source observations and multiple-model simulations to quantify lake heat storage and its impacts on lake evaporation in the ice-free period for Yamzhog Yumco, an alpine deep lake in the southern Tibetan Plateau. We first calculate lake heat storage based on a regression relationship between the modeled (Rn - G) and EC-observed (H + LE) to deal with the energy non-closure problem inherent in the EC system. Then, we quantify lake heat storage's impacts on evaporation using multiple evaporation estimation models with lake heat storage considered or not and observations of three types of evaporators. The PE-III model can optimally estimate lake evaporation when considering lake heat storage. By contrast, the average daily evaporation is overestimated before early October while underestimating afterward with models neglecting lake heat storage, peaking 4-6 months earlier than EC observation. Besides, the observed evaporation differences between the EC technique and three types of evaporators vary with the evaporator scale related to heat storage magnitude. We also reveal that net radiation and heat storage capacity jointly control lake heat storage, whose impacts on lake evaporation are prominent when deepening lake depth. Our findings provide a framework to quantify lake heat storage and its impacts on lake evaporation over alpine deep lakes lacking water-temperature- profile observations, hopefully improving the accuracy of lake evaporation estimation and deepening the understanding of lake water and heat balance. |
