Relative humidity be de ratio of how much water vapour dey insyd de air to how much water vapour de air fi potentially contain at a given temperature. E dey vary plus de temperature of de air: colder air fi contain less vapour, den water go tend make e condense out of de air more at lower temperatures. So dey change de temperature of air fi change de relative humidity, even wen de absolute humidity remain constant.

For scientific notion insyd, dem dey define de relative humidity ($RH$ anaa $\varphi$) of an air-water mixture as de ratio of de partial pressure of water vapor ($p$) insyd air to de saturation vapor pressure ($p_{s}$) of water at de same temperature, usually dem express as a percentage:$$\varphi =100\%\cdot p/p_{s}$$
