  "term": "Solenoid",
  "field": "Meteorology and atmospheric science",
  "definition": "A three-dimensional curve that forms a closed loop, often used in meteorology to describe the intersection of isobaric and isosteric surfaces. In atmospheric dynamics, a solenoid represents a tube enclosing a region where pressure and density surfaces intersect. The number of solenoids within a given area indicates the baroclinicity of the atmosphere.",
