100%.

The dew point of air is the temperature at which the air will become saturated. Saturation describes the condition of the air when it contains the maximum possible amount of water vapor. Relative humidity describes the percentage of the maximum possible water vapor content that the air holds at a given time (For example, the air may be able to hold 10 g/m3 of water vapor at a given temperature. It it contains 3 g/m3, it contains 30% of the maximum, so its relative humidity is 30%). When air reaches its dew point, it has become saturated. This means that the air now holds the maximum amount of water vapor possible -- 100% of the maximum. Therefore, relative humidity at the dew point is always 100%.

Dew point is the temperature when (invisible) water vapor in the air starts to condense. Relative humidity is the amount of water in the air. If someone knows the relative humidity, they can compare it to the dew point and figure out how wet it will be or if it will rain.


relative humidity is the AMOUNT of water in the air. Dew Point is the TEMPERATURE at which the water vapor in the air is turned into liquid water.


When the air temperature reaches the dew point, water droplets that are in the air become visible. This is how you would get fog. Relative Humidity goes soaring to near 100%.


relative humidity increases.



relative humidity is 100 percent.



The dew point is the temperature at which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation temperature.The dew point is associated with relative humidity. A high relative-humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decreaseTherefore, by the above stated reasons (of humidity and barometric pressure and saturation based on temperature) are all reasons the point at wick dew forms is not the same because the regions them selves vary and thus these relative factors maybe dissimilar.


condensation Another question that follows: As an air mass cools to its dew point; relative humidity increases


I know there is relative humidity (the amount of moisture in the air) and dew point (the temperature in which dew is formed) they both fit in with humidity.


The polar air has a high relative humidity due to the temperature of the polar region being close to the dew point temperature. The closer the dew point temperature is to the surrounding temperature, the higher is the relative humidity. The air in the polar region is considered dry as the dew point temperature is low. Low dew point indicates low water vapor content. So since the dew point in the north pole is low, it has a low water vapor content in the air, resulting in it being dry.


Temperature of polar is such low and much closer to the dew point, so the relative humidity is high. But low dew point let little water vapor be hold by the air, so it is dry.

Dew point is measured by measuring relative humidity. When the humidity has been determined, a series of mathematical equations is used to figure out the dew point.


Absolutely. Air which is close to the ground cools overnight. While the air is cooling, the relative humidity is increasing until it reaches the dew point and water is released. Transpiration can also cause the dew point to be reached by increasing the relative humidity. This is why there is much more dew on the grass than on pavement.


The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.


A hygrometer measures dew point and relative humidity, or how dense water vapor is in the air.


The greater the air temperature, the more moisture can be absorbed, which is why humidity is referred to as "relative humidity". The "dew point" or the point where the moisture condenses out of the air varies.


When the relative humidity and dew point temperature are the same they form clouds.


It is a function of the "dew point" of the air at any given moment. If relative humidity is high, the dew point will also be high and the swamp cooler air will be relatively warm. If relative humidity is low, the dew point will also be low and the swamp cooler air will be relatively cold. A swamp cooler in Phx AZ will put out air about 30 degrees less than the outside air, and works more efficiently when the humidity outside is very low.




The dew point depends on relative humidity. By measuring the dew point, scientists can determine what the weather will be like in the upcoming days.


The Dew Point is a measurement of the water vapor in the air … the Humidity.


Dew Point Dew point, where a particular temperature. Relative Humidity and atmospheric pressure combine to form water drops on surfaces.
