  "id": "MLC-T-MET-009439",
  "term": "Surface of constant phase",
  "field": "Meteorology and atmospheric science",
  "definition": "An imaginary surface in a wave field where all points have the same phase of oscillation at a given instant in time. For a plane wave, this surface is a plane perpendicular to the direction of wave propagation. In more complex wave patterns, these surfaces can be curved, representing the wavefronts of the disturbance.",
