  "term": "Friction head",
  "field": "Meteorology and atmospheric science",
  "definitions": [
    "The equivalent height of a column of fluid that represents the energy lost due to frictional resistance as the fluid flows through a conduit or across a surface. This concept is more commonly applied in hydraulics and fluid mechanics than directly in atmospheric science. It quantifies the pressure drop caused by viscosity and turbulence.",
    "In hydrologic terms, the decrease in total head caused by friction"
