How can a location with a lower relative humidity (RH) have a higher actual water vapor content than a location with a higher relative humidity?
The answer lies in the definitions of relative humidity and actual water vapor content. Relative humidity is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor that can evaporate into the air before condensation begins to occur. It is usually expressed as a percent. Water vapor content is the quantitative amount of water vapor present in a parcel of air. This is expressed as a unit of weight such as grams.
