Statistical postprocessing<br />

◮ Marginal distributions:<br />

Conditional on weather forecast<br />

Standard ensemble postprocessing<br />

◮ Ensemble MOS (e.g., Wilks, 2006; Gneiting et al., 2004)<br />

◮<br />

◮<br />

Ensemble dressing – Ensemle kernel dressing (e.g., Wang and<br />

Bishop, 2004; Broecker and Smith, 200)<br />

Bayesian model averaging (e.g., Hoeting et al, 1999; Raftery et al,<br />

2005)<br />

◮ Dependence structure:<br />

Transformed Gaussian random fields (e.g., Berrocal et al., 2008)<br />

Max-stable random fields (e.g., Kabluchko et al., 20098)<br />
