What amount of water vapor is present in the air?

The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure. read more

_____ measures the amount of water vapor present in the air to the maximum possible water vapor content at the current temperature Relative humidity The _____ is the temperature at which saturation occurs (or would occur) in a given air parcel. read more

This is known as the"humidity" of the air. Warmer air can hold more water than colder air. The percentage of water vapor in the air, compared to the maximum amount possible at that temperature, is called the relative humidity. Air that contains 100% of the possible water vapor is said to be saturated. read more

1. Water vapor must be present in sufficient amounts so saturation can occur 2. Cloud condensation nuclei (CCN) must be present to provide a surface so water will condense 3. Cooling mechanism is required to cool the air temp. to the dew point temp. read more
