 Compound events or rare combinations of weather and climate drivers can have significant societal impacts. To understand these impacts, it is necessary to analyse data with very large sample sizes. This requires single model initial condition large ensemble, smile, simulations from multiple climate models, which provide hundreds to thousands of years of weather conditions. By combining smiles with an improved physical understanding of compound events, we can provide practitioners and stakeholders with the best available information on climate risks.
