What does relative humidity mean?

Answer 1

It tells you how much your relatives are sweating .. relatively speaking. Good Luck ! :)

Answer 2

Technical:
vapor pressure, water vapor mixing ratio, or specific humidity divided by the saturation vapor pressure, saturation water vapor mixing ratio, or saturation specific humidity, respectively, expressed as a percentage.

Non-technical:
The relative humidity indicates how easy it is for liquid water to evaporate to form water vapor.

RH < 100: Water will evaporate, and evaporation will occur more rapidly the lower the RH is.
RH > 100: Water vapor will condense to form liquid water.
RH = 100: Water will neither condense, nor evaporate.

Answer 3

Relative humidity is the percentage measurement you get when you watch the weather channel. It shows how much water the air is holding based on its maximum capacity. Absolute humidity is different.

Answer 4

it's the amount of moisture in the air. The relative humidity is higher in the winter time because the dewpoint is lower. You never have a relative humidity of 100 percent in the summer, unless you live in a cool climate.

Answer 5

I think it means how much water vapor is in the air, but, here's the real definition:


the amount of water vapor in the air, expressed as a percentage of the maximum amount that the air could hold at the given temperature; the ratio of the actual water vapor pressure to the saturation vapor pressure.

Answer 6

RH is the ratio of the actual moisture vapor in the air to the saturation level for that temperature and pressure:
