One definition of dry air is a theoretical sample of air that has no water vapor. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. Relative Humidity: (Humidity) - The ratio of the actual amount of water vapor in the air to the possible amount at that temperature. The remnants of these storms occasionally recurve and move into the mid-latitude westerlies, bringing considerable moisture with them. Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air .
