Mixing time of the ocean

Web2 dagen geleden · 1 Introduction. Intense turbulent mixing characterizes the ocean surface boundary layer during wind events. The level of turbulent kinetic energy (TKE) near the surface determines momentum, energy, and tracer fluxes at the air-ocean interface (e.g. D’Asaro, 2014).As a consequence, turbulent mixing also determines how surface … Web19 jan. 2024 · This implies that STF-induced mixing in the oceans is largely determined by this “depth ratio,” which is defined as the ratio of the thermocline thickness to the ocean depth. By applying experimental data to real oceans, we estimate that the STF-generated mixing rate in the oceans is only about , which is 1 order of magnitude smaller than the …
