So berechnen Sie Dew Point
learn.whatIsHeading
The dew point is the temperature to which air must be cooled for water vapour to condense. Unlike relative humidity, dew point is an absolute moisture measure that stays constant when temperature changes.
Formel
Schritt-für-Schritt-Anleitung
- 1Uses the Magnus formula: alpha = ln(RH/100) + (a × T)/(b + T)
- 2Constants: a = 17.625, b = 243.04 degrees C
- 3Dew Point = (b × alpha) / (a − alpha)
- 4Dew point above 21°C feels humid; above 24°C feels oppressive
