“Modified inertial range power laws due to finite spectral bandwidth: idealized modeling results and implications for waves in the ocean”

Oliver Bühler (NYU Courant) will present at the 2022 Simons Collaboration on Wave Turbulence Annual Meeting on December 1st and 2nd in New York.

“Modified inertial range power laws due to finite spectral bandwidth: idealized modeling results and implications for waves in the ocean”:

Predictions for power laws from wave-kinetic theory are  based on infinite spectral bandwidth, with arbitrarily large scale separations assumed to hold between forcing and dissipation scales, for example.  We show by way of very high resolution numerical simulations of an idealized model that large but finite spectral bandwidth has a strong and predictable impact on the observed power laws.   This has  practical implications for  the interpretation of  experimental results and field observations, and the relevance of this  for the study of realistic ocean waves is discussed.
