The short answer is the maximum percentage of humidity in the air at any temperature is 100%.
The percentage of humidity or relative humidity of air is the percent of the maximum humidity or amount of water that the air can hold at any given temperature. Therefore if the relative humidity is 80 per cent at 20 degrees and then the air cools off to 18 degrees the relative humidity goes up even though the amount of humidity or water in the air stays the same. If the temperature continues to drop the relative humidity will continue to rise. Since cool air can hold less air than warm air the relative humidity will eventually reach 100%. If the temperature continues to fall the relative humidity will remain at 100% and water will come out of the air as precipitation.

What percentage of humidity is considered low?
Around 20% is considered low. 30% to 40%, whilst on the dry side, are tolerable. 50% is comfortable, though that percentage can feel quite humid when the temps are high.
What term is defined as the amount of water vapor in the air compared to the amount of water that the air can hold?
This is the measure of relative humidity. At 50 percent relative humidity, the air is holding half of what it could. It is relative humidity because it is related to the temperature and pressure of the air.
What term indicates the moisture content of the atmosphere measured as a percentage of saturation?
relative humidity
What is humidity and how is it affected by temperature and pressure?
Simply humidity is percentage of moisture in atmosphere or in a gas.When temp. increases pressure reduces, that means gas percentage reduces in unit volume. But due to latent heat of water vapor expansion of vapor is less which results in increase in humidity. And when temp reduces, gaseous volume increases result in less humidity. The above case is for constant water vapor in air. If rain is there humidity increases because of chance of getting to water vapor is more.
How can relative humidity and dew point be used to predict the weather?
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
What are humidity measurements based upon?
Air humidity measurements are based on the water content of the air, expressed as volume percentage: Relative Humidity = percentage of saturation at a given temperature Absolute Humidity = percentage of water in the air, regardless of saturation or temperature. The humidity that is talked about in weather reports, is relative humidity.
What is the humidity percentage on mars?
100% humidity. I am a professor at Brown University.
What was the percentage of humidity?
0 degree
Is humidity a percentage?
Yes, humidity is expressed as a percentage. When the dewpoint and the humidity are nearly the exactly the same or exactly the same as the air temperature, you'll have fog. The higher the dewpoint, the more humid it will feel.
What percentage of humidity is it when the air is saturated?
100%
Measure of humidity?
Relative humidity and is expressed as a percentage. Absolute humidity is expressed as a concentration - mg/L. Specific humidity is a ratio of masses - water to air in a finite volume.
What percentage of humidity does the tornado have?
It is 80 percent or over.
How can you read humidity on chart reading?
To read humidity on a chart, locate the humidity scale on the chart. Typically, humidity will be represented as a percentage. Identify where the data point falls on the scale to determine the humidity level at that particular time.
What things are true about relative humidity?
the things that are true about it is that it is a percentage
Why is it dry in Death Valley of California?
it is low in humidity percentage
Is relative humidity expressed as a fraction?
It is expressed as a percentage (fraction of 100%).
What percentage of humidity occurs if water can no longer evaporate into the air?
12
