6. Glossary

Humidité absolue; absolute humidity

This is the ratio of the mass of water vapor to the total volume of humid air.

Humidité relative; relative humidity

This is the ratio of the partial pressure of water vapor to the partial pressure of water vapor in saturated humid air at the same pressure and temperature.

Humidité spécifique; specific humidity

This is the ratio of the mass of water vapor to the mass of humid air in which the water vapor is contained.

Pression de vapeur saturante; saturation vapor pressure

This is the vapor pressure in a state of indifferent equilibrium with a flat surface of liquid water or ice at the same temperature and pressure. In other words, it's the maximum value that the partial pressure...
