  "term": "Constancy",
  "field": "Meteorology and atmospheric science",
  "definition": "A wind statistic equal to the ratio of the magnitude of the vector mean wind to the mean wind speed averaged without regard to direction, usually written as a fraction or percentage. A value near 1 means the wind blew steadily from one direction, while a value near 0 means the directions varied so widely that they largely cancelled. It is also called directional constancy or steadiness.",
