what is the relationship between air temperature and relative humidity
A: The warmer air is, the more water vapor it can hold.. Dew point is a measure of how much water vapor is actually in the air. Relative humidity is a measure of the amount of water in the air compared with the amount of water the air can hold at the temperature it happens to be when you measure it.: The amount of water in the air is given by absolute humidity, typically measured in grams per cubic meter. Relative humidity is a ratio of how much water vapor is in a given volume of air compared with the amount of water vapor that would saturate the air at a given temperature and pressure.
