What weather factor is a hygrometer use for?
Hygrometers measure the relative humidity of the atmosphere. The relative humidity is the ratio between the present water vapor content of the air and the maximum amount of water vapor the air could hold at the same temperature. Cool air will not hold as much water vapor as warmer air. With the same amount of moisture in the air, an increase in temperature decreases the relative humidity, and if the temperature drops, relative humidity increases.
What is the ratio of how much water is in the air compared to how much it can hold at that temperature?
This is known as the relative humidity (although ecologists may refer to it as the water vapour pressure deficit).
How much us high relative humidity?
Relative humidity is 100% of water vapor in the air. When that happens dew forms.
Why is there high relative humidity in basements in the summer?
1) Warm air can hold/contain more water vapor than cool air. 2) Relative humidity is a measure of how much water is in the air as compared to the maximum it can hold. Thus if you take some warm summer air and send it into a nice cool basement, the air will cool and as cool air can hold less water than the warm air, the relative humidity of the cooled air in the basement will go up.
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.

How much water vapor is needed to saturate the air?
This is called the relative humidity. It changes due to evaporation and precipitation, and warm air can hold more water than cooler air.
What is absolute and relative humidity?
Relative Humidity (RH), is how much water vapor is in the air at a certain time. Humidity, in my opinion, is just another way of saying how much water vapor is in the air.

What is relatives humidity?
Relative humidity is the volume of water vapor in a sample of the air, compared to the maximum that the air can hold at the given temperature, expressed as a percentage. Water can "dissolve" in air. As the temperature and pressure of air goes up, the amount of water that can be held in the air increases. We can measure the "absolute" humidity of air, but this isn't especially useful. It is more handy to know how much water is IN the air, as a percentage of the amount of water the air COULD hold. That's "relative humidity". It is important because as the temperature rises, the air COULD hold more water, so the relative humidity falls. As the temperature falls, the relative humidity rises. As the air cools, when the air can't hold any more water than it has now, the relative humidity is 100%, and we call this temperature the "dew point", when dew will begin to settle onto the grass. If the air gets much colder, the water will condense out of the air and form FOG. In some cases, the air can hold more moisture than it ordinarily would, which is referred to as supersaturation, which is much more common at temperatures below the freezing point.
How is relative humidity the same as humidity?
both are measures of how much water vapour is in the air
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 gives you a percent indicating how much water vapor is in the air?
The humidity. Or, if you're watching the weather report on tv, the relative humidity is used. This is a measure of how much water is in the air versus the maximum amount of water the air can hold (the saturation point).
Why does Relative Humidity increase when air cools?
Relative humidity is a measure of how much moisture is in the air relative to how much the air can hold. All the matters in the case of the latter is the air temperature. So if you cool the air temperature, the air can hold less moisture. Therefore, the air now has a larger percentage of moisture relative to what it can hold.
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
