  "id": "MLC-T-MET-010245",
  "term": "Wind crust",
  "field": "Meteorology and atmospheric science",
  "definition": "A hard, dense layer on the surface of a snowpack, formed by the mechanical action of wind. The wind breaks down individual snow crystals and packs them tightly together, creating a firm surface without necessarily involving melting and refreezing. This crust can support the weight of a skier but is distinct from a melt-freeze crust, which forms from the refreezing of surface meltwater.",
