Fig. 3: Long-term trends of global lake evaporation.
a The nine lake thermal regions defined in Maberly et al.21 b Long-term trends of lake evaporation rate (Elake) for the nine regions. c Long-term trends of lake open water area (Ao) for the nine regions. d Long-term trends of evaporation volume (VE) for the nine regions. Each sub-panel shows the annual time series from 1985 to 2018—and its trend—for the corresponding thermal region. All values for Elake, Ao, and VE are shown as a percentage (which is the actual value divided by the long-term averaged value). The trend indicated in each sub-panel was calculated based on the annual percentage values using a linear regression. Values without an asterisk are significant (p-value < 0.05) and values with an asterisk are not.
