This page shows the validation plots for Efate.
Model validation was carried out in order to check the models accuracy against the measured waves.
In Efate, waves were measured during a long period of time (22/11/1990 - 12/02/1993) at only one location shown on the map below.
The map below shows the location of the wave buoy south of Efate in a region exposed to south swells and trade wind waves.
The tables below shows the Root Mean Square Error, skill and Bias of the model.
The model skill is very close to 0.9 which means the model is accurate. The model has a relatively large bias probably due to unresolved bathymetry features. The RMS is within the expected error for this type of model.
The scatter of the comparison and the quantile show a more detailed analysis of the models' performance.
The scatter plot shows the divergence between the model and measurements. The spread of the scatter is relatively uniform across all the measured wave heights suggesting that the model is valid for wave heights between 0.0m and 5.0m. The quantile/quantile plot shows how the bias varies with different wave heights. The bias is relatively small for wave heights below 5.0m which corresponds to all the trade wind waves and swells. Larger waves are often created by nearby cyclones which are not well resolved in the model.
