The study analyzed how climate affects evaporation on Lake Nasser in Egypt over 10 years. They used data from weather stations and radiation measurements to estimate evaporation rates. The average evaporation rate was 5.88 mm per day, with significant variability on different timescales. Evaporation changes were linked to weather patterns, temperature, and energy transfer. Seasonal changes were driven by temperature and energy, while intraseasonal changes were related to weather variations. Interannual changes in evaporation were mainly influenced by energy transfer.
