Tīmeklis2024. gada 18. maijs · Rank histograms are popular tools for assessing the reliability of meteorological ensemble forecast systems. A reliable forecast system leads to a uniform rank histogram, and deviations from uniformity can indicate miscalibrations. However, the ability to identify such deviations by visual inspection of rank histogram plots … Tīmeklis2011. gada 1. janv. · 1. Introduction. The verification rank histogram (RH; Anderson 1996; Hamill and Colucci 1997; Talagrand et al. 1997) is a commonly used diagnostic for ensemble forecasts of scalar predictands.For each of a collection of n ens-member forecast ensembles, the ensemble members and the verifying observation are jointly …
