What type of air has a realative humidity of 100 percent?
That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.
Why polar 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.
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.
How much relative humidity would decrease when temperature rises?
Relative humidity is a ratio between the partial pressure of water vapor and the saturation pressure of water vapor at the current temperature and pressure. If the temperature and pressure change, then the relative humidity will change also. You are correct that higher temperatures allow the atmosphere to hold more water. That means that the saturation pressure of water vapor has increased while the current vapor pressure has remained the same, causing the relative humidity to drop. We think of humidity as how hot and sticky it is outside. The closer the water vapor pressure is to its saturation point, the more hot and sticky we feel. We associate humidity with heat since that is when we are uncomfortable, but rain is caused by the relative humidity rising to 100% because the humid air cooled to the point that the saturation pressure dipped below the current vapor pressure (or other pressure changes, or a combination of both).

What would Mars' orbit be if it orbited 96 percent closer to the sun than it does now?
If Mars orbited 96% closer to the sun than it does now, it would orbit at an average distance of 5,664,000 miles (9,115,324 km).

What happens when the air temperature and the dew point temperature are close together?
When both come closer,relative humidity increases;When they are almost equal,condensation water vapour begins.

Why is the dew point never the same?
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.
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.
At what temperature can a person see his breath?
When you breath out, you always breath out water vapor along with air. However, you can't usually see the water vapor because the water molecules are not close enough to form individual droplets. Individual droplets can be seen at the dewpoint.The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. If the relative humidity is 100%, the dew point is equal to the current temperature.Cool air can hold less moisture, which is why dew forms on the ground overnight, when the air cools.Back to your question:If the air has a higher humidity, you'll be able to see your breath at a higher temperature.If the air has low humidity, it will take a cooler temperature to be able to see your breath.This is why you can see your breath in the winter much more easily than in the summer.
What makes extreme weather in deserts?
Lack of humidity and clouds cause the temperature extremes. Humidity and clouds act as a blanket which prevents an area from heating up as much during the day and cooling down as much when the sun sets.
How close to the sun would Mercury be if it orbited 96 percent closer than it does?
Mercury's orbit would be, on average, 1.44 million miles (2.3 million km) if it orbited 96% closer than it does.
What would the orbit of Venus be if it orbited 96 percent closer to the sun than it does?
If Venus orbited 96% closer to the sun, it would orbit at an average distance of 2.69 million miles (4.33 million km).
What would Earth's orbit be if it orbited 96 percent closer to the sun than it does?
If Earth orbited 96% closer than it currently does, its orbit would be, on average, 3.72 million miles (6 million km).
