When air is cooled what happens to Relative Humidity?
Yes. Relative humidity is the amount of water vapor actually in the air compared to the amount that could be in the air (saturation point) at the exisiting temperature. So, if the temperature of the air changes and the amount of water vapor in it does not, the relative humidity will be different. But, if the temperature of the air changes and so does the amount of water vapor in it, then the relative humidity could be the same as before the temperature change. That is to say that the air could contain the same percentage of water vapor that it could hold at each temperature, even though the actual amounts are different.
How can relative humidity and dew point be used to predict the weather?
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
During a clear calm day the relative humidity will tend to BLANK from sunrise to early afternoon?
During a clear calm day, the relative humidity will tend to decrease from sunrise to early afternoon as the air temperature rises and air is able to hold more moisture.
How does a change in temperature affect relative humidity and specific humidity?
When the temperature of air is cooled or reduced the relative humidity (RH) increases. The moisture content of the air remains the same until the RH rises to the point of 100% saturation and condensation occurs.
What causes an air parcel to cool as it rises in the atmosphere?
An air parcel cools as it rises in the atmosphere due to a decrease in air pressure. As the parcel moves to higher altitudes, the lower pressure causes it to expand, which leads to a decrease in temperature. This process is known as adiabatic cooling.
How does relative humidity change with temperature?
As temperature increases, relative humidity decreases. This is because warmer air can hold more moisture, so the relative humidity percentage decreases as the air temperature rises.
What term refers to the temperature at which the relative humidity is 100?
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 happens to relative humidity when temperature rises?
When temperature rises, the capacity of air to hold water vapor increases. Consequently, the relative humidity decreases because the amount of moisture present in the air remains the same, but it is spread out over a larger volume.
What is the effect on relative humidity when the temperature of a body of air increases?
When the temperature of a body of air increases, its relative humidity decreases. Warmer air can hold more moisture, so as the temperature rises, the air can distribute the moisture more evenly and the relative humidity decreases.
WHAT HAPPENS WHEN THE Parcel air expands?
When parcel air expands, it becomes less dense and rises in the atmosphere. As it rises, it cools and condenses, forming clouds and potentially leading to the development of precipitation. This process is integral to the creation of weather patterns such as rain and storms.
Why does relative humidity decrease after the sun rises and increase after the sun sets?
"Because relative humidity is related with the temperature of the air. Relative humidity is the rate of water vapour to the maximum amount of water vapour can air hold at that temperature. The amount of water vapour that air can hold is increses as the temperature of the air increases. If the air holds same amount of water while the temperature is incresing, relative humidity of the air decreses because maximum amount of water that air can hold increases and the rate of humidity to tha maximum humidity decreses."Someone had given this answer, and it is partially correct, however, their bizarre English and grammar skills make it hard to understand. I think what they meant was that relative humidity is the amount of water vapor in the air, compared to what the air can "hold" at a given temperature. As temperature increases, the amount of water vapor or moisture the air can hold does as well.So, after the sun rises the temperature of the air increases, so does the amount of moisture the air can hold and the actual amount of water vapor in the air may stay the same, thus decreasing the relative humidity. The opposite happens at night.Relative humidity = (actual vapor density/ saturation density) x100%
What happens if the dollar price of yen rises?
the dollar depreciates relative to the yen.

What happens with altitude relative to pessure?
as altitude rises less there is less atmospheric pressure

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.
When warmer air rises above the frontal surface expands and cools as it ascends does it relative humidity increase or decrease?
When warmer air rises above the frontal surface, it expands and cools as it ascends. As the air cools, its relative humidity increases because cooler air has a lower capacity to hold moisture, leading to saturation and potentially precipitation.
