dc.description.abstractHigh‐resolution global ocean models forced by atmospheric fields and tides are beginning to display realistic internal gravity wave spectra, especially as model resolution increases. This paper examines internal waves in global simulations with 0.08° and 0.04° (~8 and 4 km) horizontal resolutions, respectively. Frequency spectra of internal wave horizontal kinetic energy in the North Pacific lie closer to observations in the 0.04° simulation than in the 0.08° simulation. The horizontal wave number and frequency (K‐ω) kinetic energy spectra contain peaks in the semidiurnal tidal band and near‐inertial band, along with a broadband frequency continuum aligned along the linear dispersion relations of low‐vertical‐mode internal waves. Spectral kinetic energy transfers describe the rate at which nonlinear mechanisms remove or supply kinetic energy in specific K‐ω ranges. Energy is transferred out of low‐mode inertial and semidiurnal internal waves into a broad continuum of higher‐frequency and higher‐wave number internal waves.Key PointsRepresentation of internal gravity wave spectra in OGCMsSpectral internal gravity wave kinetic energy and nonlinear energy transfersNonlinear internal wave‐wave interactions in the wave number frequency domainen_US
