Abstract: Statistical post-processing techniques serve to improve the quality of numerical weather forecasts, as they seek to generate calibrated and sharp predictive distributions of future weather quantities and events. I will review the state of the art in post-processing, with focus on ensemble forecasts and ongoing joint work between the ECMWF and the Computational Statistics group at the Heidelberg Institute for Theoretical Studies (HITS). Current and future challenges include the treatment of extreme events, and the calibration of probabilistic forecasts of combined events and spatio-temporal weather trajectories, for which discrete copula based techniques, such as ensemble copula coupling (ECC) and the Schaake shuffle, are attractive options.
