Chain rule

  "id": "MLC-T-MET-004244",
  "term": "Chain rule",
  "field": "Meteorology and atmospheric science",
  "definition": "A fundamental rule of calculus for differentiating a composite function, which is a function of another function. The rule states that the derivative of f(g(x)) is the derivative of f with respect to g multiplied by the derivative of g with respect to x. This principle is applied extensively in atmospheric models for tasks like coordinate transformations and calculating the total derivative of a variable following fluid motion.",
