  "term": "Local change",
  "field": "Meteorology and atmospheric science",
  "definition": "The rate of change of an atmospheric variable at a fixed point in space over time, as observed by a stationary instrument. This is represented mathematically by the partial derivative of the variable with respect to time. Local change is distinct from the advective change, which describes the change due to the movement of air parcels with different properties into the fixed point.",
