  "id": "MLC-T-MET-008534",
  "term": "Resonance trough",
  "field": "Meteorology and atmospheric science",
  "definition": "An elongated area of relatively low atmospheric pressure that forms and persists due to resonance between atmospheric flow and underlying topography. This occurs when the wavelength of an atmospheric wave matches a characteristic length scale of a mountain range. Such troughs can lead to persistent weather anomalies downstream of the mountains.",
