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 else can I help you with?
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
What is the relative humidity during a blizzard?
Since it's usually snowing, the relative humidity is near 100%.
What are the basic characteristics used to describe air mass?
Air masses are described based on their temperature and humidity characteristics. These characteristics are categorized as maritime (moist) or continental (dry), and polar (cold) or tropical (warm). The combination of these factors gives rise to different types of air masses, such as maritime tropical or continental polar.
What happens to relative humidity as a parcel or air rises?
As a parcel of air rises, it expands and cools adiabatically. This cooling causes relative humidity to increase, as the air temperature drops and its capacity to hold moisture decreases. If the air parcel reaches its dew point temperature, the relative humidity will reach 100% and condensation or cloud formation may occur.
Which type of air mass brings cold dry weather to the northeast?
The type of air mass that brings cold, dry weather to the northeast is a continental polar air mass, which forms over cold, polar regions and brings cold, stable air with low humidity. When this air mass moves southward into the northeast, it typically brings clear skies and cold temperatures.
Why is the cold air described as dry when the relative humidity of that air is very high?
Cold air can hold less moisture than warm air, so when cold air is heated, its relative humidity decreases because the moisture content remains the same but the air's capacity to hold moisture increases. This is why cold air is often described as dry, even if the relative humidity is high.
Why polar air described as dry when the relative humidity of that air is very high?
Polar air is considered dry because it has low absolute humidity due to its low temperatures. Despite having high relative humidity, the total amount of water vapor in the cold air mass is still less compared to warm air masses. This makes it feel dry and can lead to issues like dry skin and static electricity buildup.
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?
The average relative humidity in winter in Flint, Michigan is around 75-80%. This level of humidity is considered high and can contribute to the cold feeling during winter months.
Why do people use coasters when setting cold drinks on furniture to protect the surface from?
Relative humidity
Would you expect polar air to have high or low humidity?
Polar air typically has low humidity because cold air has a limited capacity to hold moisture. As the air temperature drops in polar regions, the air becomes drier.
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.
Is the humidity high or low in a continental polar air mass?
Humidity is typically low in a continental polar air mass because this air mass originates from high latitudes where the air is cold and dry.
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.
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.
What is the environment like in Antarctica?
Antarctica is a polar desert, very cold, mountainous and extremely icy
In the winter cold air is brought into homes and heated how does this change the relative humidity?
