Taylor Diagrams

Taylor diagrams summarize the skill of the two models in capturing the HF Radar datasets. The data has been grouped by region (Figs. 90 and 91). Correlations are higher for the northward tidal component of velocity, which is most along-channel oriented for the HF Radar areas, than for the eastward component, and CIOFS Hindcast and Fresh perform similarly. The subtidal components are poorly captured by both models: low correlations for the eastward component and even lower and negative (not shown on plot) for the northward component. Skill scores are shown in the next plots for each dataset.
