Because warm air can carry more moisture than cold air. The relative humidity level will be higher in cold air and lower in warm air at the same absolute humidity level.

The large glass with a temperature of 100 degrees and a relative humidity of 50% corresponds to a 78 degree dew point. This is much more humid than the small tank where the dew point is only 41.

We’ll start with humidity because that’s a term most of us have heard since we were children. Humidity can be discussed in two ways… Absolute Humidity and Relative Humidity.

Relative humidity is the ratio of air water vapor content to the saturating level, which itself varies with temperature, while absolute humidity quantifies the actual amount of water in the air ...

In your first meteorology course, you’ll come to learn that there are two main types of humidity: absolute and relative. Absolute humidity is the measure of water vapor, or moisture, in the air ...

This happens at night or in the morning, and this is when the humidity gets close to 100%. The definition of relative humidity, as defined by the National Weather Service office in Louisville, is ...

Link Found Between Influenza, Absolute Humidity Date: February 10, 2009 Source: Oregon State University Summary: A new study has found a significant correlation between "absolute" humidity and ...

Absolute humidity is expressed in weight of water, grams or pounds, in a volume of air, such as a cubic meter or yard. The higher the reading the wetter. The wetter, the worse for flu virus.

The definition goes on to say that, "relative humidity by itself does not directly indicate the actual amount of atmospheric moisture present." Here's the problem.

The temperature and dew point temperature match at 52 degrees. "52 over 52" produces a relative humidity of 100%. In the afternoon, the sun warms the temperature to a mild 72, but the dew point stays ...

Relative humidity has substantially declined in recent decades, defying global warming computer models predicting higher amounts of atmospheric water vapor that will exacerbate global warming.
