Upvalley wind

  "id": "MLC-T-MET-009919",
  "term": "Upvalley wind",
  "field": "Meteorology and atmospheric science",
  "definition": "A localized wind that blows up a valley during the daytime, driven by differential heating between the valley floor and the surrounding mountain slopes. As the valley floor and slopes warm, air rises, creating a pressure gradient that draws air from the lower, cooler parts of the valley upwards. This wind typically reverses to a downvalley wind at night.",
