Development and validation of a three-dimensional curvilinear model for the study of flukes through the North Channel of the Irish Sea

A three-dimensional non-orthogonal curvilinear model has been developed for the Celtic Sea, Irish Sea and North Channel. With a maximum resolution of approximately 1 km in the North Channel, the model resolves the complex topography and horizontal flow variability in this region, whilst the large geographical domain enables the inclusion of far field forcing. Predicted co-tidal charts of the region are in good agreement with published charts based on observed tidal elevations and from previous modelling studies. Comparisons of observed and predicted M2 and S2 tidal elevations and currents suggested that in general, this model is considerably more accurate than a previous large area, coarse resolution model of the region, and comparable with previous high resolution limited area models.
The predicted tidal residual flow through the North Channel of 0.026 Sv is in good agreement with previous modelling studies. Predicted tidal residual currents in the North Channel showed considerable spatial variability, clearly demonstrating the importance of a high resolution grid in this region. Of particular interest are the predictions of a strong cyclonic gyre at the mouth of Belfast Lough, and a strong southwards coastal current along the Mull of Galloway, which may in part explain the observations of fresher water in this region. The relevance of the extensive model domain is considered in a future paper where the effects of local and far field wind forcing will be discussed.
