Dynamical Downscaling

Dynamical downscaling uses high-resolution regional climate models (RCMs) to bias-correct and downscale global climate model output. This chapter discusses the models and methods used in dynamical downscaling. It provides an overview of the basic physics used in RCMs, and how this is similar to and differs from that used in global models. It also discusses the methods and metrics used to evaluate RCMs, and how projections from RCMs can be used to assess climate impacts at the regional scale
