Abstract
We introduce a determining wavenumber for weak solutions of 3D Navier-Stokes equations whose time average is bounded by Kolmogorov dissipation wavenumber over the whole range of intermittency dimensions. This improves previous works by Cheskidov, Dai and Kavlie in 2018 and that by Cheskidov and Dai in 2019.
