Скачать или смотреть Oceananigans.jl: Winds blowing over the ocean surface

An idealized simulation of a strong wind stress acting on the surface of a stratified ocean. The simulation employs a resolution of 256x256x256 volumes in a 100x100x100 m horizontally periodic domain. A pretty strong wind stress of 0.1 N/m² is applied in the x direction which mechanically mixes the upper layer of the ocean. This leads to a "mixed layer" of constant temperature near the surface of the ocean. You can also see the onset of Kelvin-Helmholtz instabilities as the mechanical mixing sets in.

The video shows the temperature field in the top 25 meters and the domain is sliced in half for visualization. The line plots show the horizontally averaged temperature profile (top right), horizontally averaged turbulent kinetic energy (middle right), and the horizontally averaged buoyancy flux (or temperature flux).

The simulated was created using Oceananigans.jl, a fast and friendly non-hydrostatic ocean model in Julia that can be run generically in 1-3 dimensions on CPUs and GPUs. The individual frames were plotted using matplotlib and the video was created using ffmpeg. This particular simulation was run on an Nvidia V100 GPU.
