Orthogonal lines

  "id": "MLC-T-MET-007749",
  "term": "Orthogonal lines",
  "field": "Meteorology and atmospheric science",
  "definition": "Lines that intersect at a right angle (90 degrees) to each other. In meteorology, this geometric concept is applied in coordinate systems and on weather maps to represent perpendicular relationships between different physical quantities. For example, on a thermodynamic diagram, isobars (lines of constant pressure) and isentropes (lines of constant potential temperature) are nearly orthogonal in the free atmosphere, indicating a stable stratification.",
