“…The correlation between these variables means that uncertainty characterization and scenario generation should address the dependency characteristics through establishment of a joint probability distribution. The copula function (Xu, Huang, et al., 2021) is applied to modeling for its superiority in formulating a multivariate joint distribution by selecting arbitrary marginals and a dependence structure.…”

“…In addition to the inherent uncertainties in GCMs, the application of GCMs to different regions needs to be assessed as it has different impacts (Zaremehrjardy et al, 2021). In essence, the forecast uncertainty can be reduced if the above-discussed uncertainties are addressed using supporting techniques (Xu et al, 2021).…”

“…At the same time, due to the influence of factors such as model parameter error, the prediction error in each period of runoff prediction has a certain correlation. In order to describe this correlation, Copula function (Xu et al 2021;Li et al 2022;Dodangeh et al 2020), Bayesian network (Lu et al 2020), Monte Carlo Markov chain (Hadfield 2010) and other methods have been applied to runoff simulation in recent years, theoretically, when the forecast period is long enough, inputting the hourly updated hydrological forecast into the operation model can update the operation decision hourly, so as to make full use of the hydrological forecast information and improve the benefits of the reservoir system (Zhao et al 2011). At the same time, combined with the simulation of uncertain factors such as runoff forecast error, the possible risks of operational decision can be better analyzed, providing clear guidance for reservoir operation.…”
