WebbRelative humidity (%RH) is a concept that defines what percentage of water vapor is present at that temperature relative to the saturation point. When it’s raining, it’s obviously 100 %RH up there in the clouds where the droplets are forming. While the instruments and technologies available to us have greatly improved over the years, the ... WebbRelative Humidity, f, is a measure of amount of moisture in the air relative to the maximum amount it can hold at that temperature. f= mv / mg(kg of H2O vapor/kg of H2O vapor in saturated air) with Pg= PSAT@T, f= Pv / Pg According to this definition: fwill always be a number between 0 and 1 ( or we can write it as a percentage)
