Webeffect of humidity is related to engine power rather than aerodynamic efficiency. At high ambient tempera-tures, the atmosphere can retain a high water vapor content. For example, at 96 oF, the water vapor content of the air can be eight (8) times as great as it is at 42 oF. High density altitude and high humidity do not always go hand in hand. WebThe altimeter setting QNH is one of the data included in METAR messages from weather stations in addition to the surface pressure. An alternative setting is QFE : QNH is the barometric altimeter setting that causes an altimeter to read airfield elevation above mean sea level when on the airfield.
