What is relative humidity in simple words? | what is relative humidity?
Relative humidity (RH) is the amount of moisture present in the air compared to the maximum amount of moisture the air could hold at a particular temperature. It is expressed as a percentage and is calculated by dividing the actual vapor pressure of the air by the saturation vapor pressure of the air at the same temperature and multiplying by 100.
In other words, relative humidity is a measure of how much water vapor the air contains relative to its capacity to hold water vapor. Warmer air can hold more moisture than cooler air, so the same amount of water vapor in the air will result in a lower relative humidity at higher temperatures than at lower temperatures.
Relative humidity is an important factor in weather forecasting and climate analysis, as it can affect human comfort, health, and safety. High relative humidity can make the air feel warmer and more oppressive, while low relative humidity can dry out skin and mucous membranes, leading to respiratory problems.
