This method is commonly used on research vessels because the inertial subrange estimates are gen-erally uncontaminated by wave-induced motion. The WebThe existence of the inertial subrange for the (incompressible) Navier-Stokes equations has been proven. In this paper, we proof the same result for any skew-symmetric regularization of the nonlinearity in the Navier-Stokes equations.

WebRecent measurements of the wind field during extreme wind events (tropical and extratropical storms) indicate that the wind speed fluctuations exhibit strong non-stationary features echoing similar observations reported at other locations. Web1 jun. 1999 · On Probing the Inertial Subrange. K. Henjes. Published 1 June 1999. Environmental Science, Physics. Boundary-Layer Meteorology. For an extensive turbulent wind speed data set collected on the open ocean, the optimum sampling time is determined to calculate inertial-range spectra. Such spectra are widely used to estimate surface fluxes.
