Fig 19 Diagnostic Characteristics of DCPP Models and Corresponding Customized Bias Correction
Strategies

This study scientifically identified the applicability and limitations of the DCPP system in
predicting extreme climate in the East Asia region. In particular, by revealing the different

data over East Asia for June-August. M1, M2, M3, M4 and M5 denote CanESM5, CMCC-
bias correction techniques. This is expected to fundamentally enhance the reliability of
CM2-SR5, HadGEM3-GC3.1-MM, IPSL-CM6A-LR and MPI-ESM1.2-HR, respectively. Yellow
stars are marked on the models with the lowest absolute bias, highest trend, highest climate prediction information and serve as a scientific foundation for more sophisticated
correlation and the lowest error. climate disaster response systems and the establishment of national climate policies.
