Over the past decades, most of global climate models, simulated ocean dynamics with horizontal resolution of about 1°. The 1-degree grid resolution is believed to underestimate contribution of small-scale ocean currents and eddies to generation of the intrinsic ocean variability and to possible upscale energy transfer in sea level
fluctuations. The lack of resolution can bias estimates of large-scale decadal and interdecadal sea level fluctuations and secular trends. Here, we use sea level simulations from the high-resolution (HR) Community Earth Model System (CESM) using a nominal horizontal resolution for the ocean of 0.1° in order to
(1) estimate the long-term trend and low-frequency (decadal and interdecadal) variability of sea level on the Western European Shelf (WES) and compare it with available observations;
(2) analyse the impact of eddies and narrow energetic currents on intrinsic variability of sea level on the WES;
(3) evaluate the contribution of upscale energy transfer to the predictability of sea level changes on the WES ;
(4) explore the projections of sea level changes on the WES in HR and LR CESM over the coming century.
