Uncertainty quantification of large models: parameters of weather and climate models
Heikki Haario
Lappeenranta University of Technology, Finland
A statistical analysis of the uncertainties of modeling, with the nonlinear models arising in engineering and science especially in mind, is becoming routine due to computational methods such as Markov chain Monte Carlo (MCMC) or Bootstrap. However, 'large' models, either in terms of CPU times or the dimension of the state, are still a challenge. We present some recent ideas how to minimize the CPU times of the sampling methods as well as to achieve low memory approximations for high dimensional problems. The primary targets here are weather prediction and climate models, studied in collaboration with FMI (Finnish Meteorological Institute) and ECMWF (European Centre for Medium-Range Weather Forecasts, UK).
