Why is cold polar air described as dry when the relative humidity of that air is very high?

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.

What happens to relative humidity as a parcel or air rises?
The relative humidity drops. This is because the temperature for the parcel of air is cold and wet which leaves enough room for some water vapor, but not a lot.
Humidity is the amount of water vapor in the air at a given time At warm temperatures air can hold more moisture than it can at cold temperatures Relative humidity is the amount of vapor the air you?
specific humidity
Which is more humid the Sahara desert on a cold night or the Texas coast on a warm day?
Texas on a warm day would have more absolute humidity, but the Sahara Desert on a cold night would have more relative humidity.
How does humidity change over 24 hours?
Cold air cannot hold as much water vapor as warm air. As temperature drops relative humidity rises. Absolute humidity remains constant until the dewpoint temperature is reached, then decreases with temperature as water precipitates out of the air. Below the dewpoint temperature relative humidity remains constant at 100%.
In the winter cold air is brought into homes and heated how does this change the relative humidity?
The relative humidity decreases. This explains why there is static and people walk around with chapped lips. Here is a link to a good explanation: http://en.allexperts.com/q/Accuweather-2546/2008/6/Physicial-Geography.htm
Why is the cold air described as dry when the relative humidity of that air is very high?
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.
What is the average relative humidity in the winter in flint?
It is cold and humid.
What is the average relative humidity in winter in Flint Michigan?
It is cold and humid.
What does relative humidity do as the temperature decreases?
As temperature decreases, relative humidity increases.** Related Information:This is why a cold front often causes precipitation as it moves through an area.
Why is it that in very cold climates indoor relative humidity can be low while the outside relative humidity can be high?
Because it's about relative humidity, not absolutehumidity. Air can carry a certain amount of moisture dependent on which temperature it is, with warmer air being able to carry more before condensation occurs. If you have two volumes of air, both containing the same amount of water, then the warm volume will be a lower relative humidity than the cold volume.

Relative humidity
How do polar bears survive in the desert?
Actually, the area that the polar bear lives is a borderline desert due to the low humidity and low precipitation. It is considered a cold desert and the polar bear has adapted to the cold and harsh conditions found there.
