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.


What are relative humidity of the locations from highest to lowest?

The relative humidity of locations can vary depending on the weather conditions, but generally, locations closer to the equator tend to have higher relative humidity levels. Coastal areas also usually have higher humidity compared to inland locations. Conversely, arid regions and high-altitude locations typically have lower relative humidity.


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.


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). You can learn more at the link below. I hope this helps.


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 happens to chance of precipitation as Relative Humidity increases?

As relative humidity increases, the chance of precipitation also tends to increase. This is because higher relative humidity indicates that the air is closer to reaching its saturation point, and clouds are more likely to form and produce precipitation.

If temperature remains unchanged and mixing ratio decreases how will relative humidity change?

If temperature remains constant and the mixing ratio decreases, the relative humidity will increase. This is because relative humidity is the ratio of the actual water vapor content in the air to the maximum amount of water vapor the air can hold at that temperature. As the mixing ratio decreases, the air becomes closer to saturation, leading to an increase in relative humidity.


What is the relationship between specific humidity and relative humidity in atmospheric conditions?

Specific humidity and relative humidity are related but measure different aspects of moisture in the air. Specific humidity is the actual amount of water vapor present in the air, while relative humidity is the ratio of the amount of water vapor present to the maximum amount of water vapor the air can hold at a given temperature. In general, as specific humidity increases, relative humidity also increases because the air is closer to its saturation point. However, changes in temperature can affect this relationship.


What happens to the relative humidity when temperature decreases but the amount of water vapor in the air stays the same?

The relative humidity percentage wil continue to rise until the dew point is achieved (100% relative humidity). This is when the proper pressure conditions are correct for the water particles in the air to accumulate causing the effect most know as "morning dew".

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.


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.
