Note: $\eta 1_{clim}$, $\eta 2_{clim}$, $\eta 3_{clim}$, $\eta 4_{clim}$ are the contribution rates of climate change in Budyko, Fu., Choudhury equations and DMC, respectively. $\eta 1_{hum}$, $\eta 2_{hum}$, $\eta 3_{hum}$, $\eta 4_{hum}$ are the contribution rates of human activities in Budyko, Fu., Choudhury equations and DMC, respectively.
