摘要：Study region Lake Ikeda, Japan. Study focus Few previous studies on the contribution of meteorological factors to lake evaporation ( E ) have been conducted with comprehensive analyses of lake surface temperature ( T s ) under different climate scenarios. This study aimed to compute and compare the sensitivities of monthly and annual E to changes in solar ( R s ) and atmospheric radiation ( R a ), air temperature ( T a ), relative humidity (RH), and wind speed ( u ) under two climate scenarios through a 36-year numerical simulation for Lake Ikeda. New hydrological insights for the region Where climate shifted unidirectionally, R s and R a were the greatest driving forces for E . The mean contributions of R s and R a to annual E change were approximated to be 2.4- and 5.4-times larger than that of T a (or RH), respectively. Thus, under warming or cooling condition around the lake, R a working with T a was dominant for E . In contrast, considering seasonal climate variability, a remarkable effect of the seasonal variability in T a on E , indicating negative correlation, was estimated. E changes were characterized by the dilatory thermal-reaction of T s , enhanced by the seasonal switching effect of heat conduction between the lake and atmosphere, and seasonal temperature dependency of vapor pressure. The driving factors of E and T s , correlations between E and meteorological factors, and variabilities of meteorological factors were compared and summarized for lakes located between 30 °N−45 °N worldwide.
