  "term": "Velocity shear",
  "field": "Meteorology and atmospheric science",
  "definition": "A change in the speed or direction of air movement over a given distance, either horizontally or vertically. This phenomenon creates turbulence and can affect the flight paths of aircraft or the development of atmospheric phenomena. Vertical velocity shear is often measured in units of meters per second per kilometer (m/s/km).",
