  "id": "MLC-T-MET-003904",
  "term": "Biennial wind oscillation",
  "field": "Meteorology and atmospheric science",
  "definition": "A quasi-periodic variation in atmospheric winds, particularly in the stratosphere, with a cycle length of approximately two years. This oscillation involves alternating easterly and westerly wind regimes that propagate downwards through the tropical stratosphere. The Quasi-Biennial Oscillation (QBO) is a prominent example, influencing global weather patterns and stratospheric chemistry.",
