We compare the stochastic behaviour of precipitation outputs of climate models for the 20th century to the historical data (stations and reanalysis fields) at several temporal and spatial scales. In particular we examine the marginal distributions and the dependence structure with emphasis on the Hurst-Kolmogorov behaviour. The comparison aims to contribute to the quantification of reliability and predictive uncertainty of precipitation climate model outputs over different scales in a framework of assessing their relevance for engineering planning and design.
