  "term": "Vapor tension",
  "field": "Meteorology and atmospheric science",
  "definition": "The pressure exerted by water vapor in a given volume of air, reflecting the concentration of water molecules. It is a direct measure of the absolute humidity and the driving force for evaporation. This atmospheric property is typically expressed in units of hectopascals (hPa) or millibars (mb).",
