  "id": "MLC-T-MET-009327",
  "term": "Strouhal number",
  "field": "Meteorology and atmospheric science",
  "definition": "A dimensionless quantity used in fluid dynamics to describe oscillating flow mechanisms, particularly those involving vortex shedding. It relates the characteristic frequency of the oscillation to the flow velocity and a characteristic length scale of the object. This number is often applied to analyze wind effects on structures or the shedding of vortices from atmospheric obstacles.",
