  "term": "Direct numerical simulation",
  "field": "Meteorology and atmospheric science",
  "definition": "A computational method that solves the Navier-Stokes equations without any turbulence models, resolving all relevant scales of motion in a fluid flow. In atmospheric science, this technique is used for fundamental research into small-scale turbulent processes, such as those in the atmospheric boundary layer. It requires extremely high computational resources.",
