Assessment of CanESM5 Decadal Hindcasts: Modes of Variability and Their Teleconnections

The Canadian Earth System Model version 5 (CanESM5), recently developed at Environment and Climate Change Canada's Canadian Centre for Climate Modelling and Analysis (CCCma), is contributing to the Decadal Climate Prediction Project (DCPP) and other components of phase 6 of the Coupled Model Intercomparison Project (CMIP6). This presentation will describe evaluations of CanESM5 decadal hindcasts against observational benchmarks and uninitialized simulations, as well as comparisons with hindcasts from CCCma's CanCM4 model that contributed to CMIP5. Emphasis is given to the assessment of predictions of interannual to decadal modes of climate variability and their teleconnections, including El Niño-Southern Oscillation (ENSO), the Pacific Decadal Oscillation (PDO), and the Atlantic Multidecadal Oscillation (AMO).
