  abstract = {{L}ow mode internal waves are able to propagate across ocean basins and modulate ocean dynamics thousands of kilometers away from their generation sites. {I}n this study, the impact of remotely generated internal waves on the internal wave energetics near the {U}.{S}. {W}est {C}oast is investigated with realistically forced regional ocean simulations. {A}t the open boundaries, we impose high-frequency oceanic state variables obtained from a global ocean simulation with realistic atmospheric and astronomical tidal forcing. {W}e use the {D}iscrete {F}ourier {T}ransform ({DFT}) technique in separating ingoing and outgoing internal tide energy fluxes at the open boundaries in order to quantify internal tide reflections. {A}lthough internal tide reflections are reduced with increasing sponge viscosity and/or sponge layer width, reflection coefficients (lambda) can be as high as 73%. {I}n the presence of remote internal waves, the model variance and spatial correlations become more in agreement with both mooring and altimetry datasets. {T}he results confirm that an improved internal wave continuum can be achieved in regional models with remote internal wave forcing at the open boundaries. {H}owever, care should be taken to avoid excessive reflections of internal waves from the interior at these boundaries.},
