as the temperature decreases, does relative humidity increase, decrease, or stay the same.?

Answer 1

With all other things remaining the same, relative humidity will increase as temperatures decrease.

Since relative humidity is a ratio (in percent) of the actual amount of water vapor in the atmosphere compared to the saturation amount, if the saturation amount decreases, the ratio must increase.

Answer 2

Relative humidity generally decreases if temperature increases.
If we say that air is saturated it means that the air is holding maximum amount of water vapour it can hold.In this condition,the relative humidity will be 100 percent.
Air will become saturated if the air temperature is brought down to its dew point temperature.In other words, this means that the relative humidity goes up( to 100 percent) if the temperature is decreased.Of course there is one condition ;the moisture content should not change during this process.
I have noticed that when the maximum temperature is recorded in the Barograph(an instrument which continuously records the temperature values for a day),Minimum humidity value is recorded in the Hygrogrph which continuously records the humidity values for the particular day.

Answer 3

Actual humidity stays the same; saturated vapour pressure decreases; so relative humidity increases. Thus daytime hot dry desert air can shed dew at night.

Answer 4

Depending on the time of year, in the summer, humidity tends to decrease as the temperature goes up, but in the winter time, that can change, when it's raining, the humidity goes up, no matter if the temperature goes up or not.

Answer 5

It is all dependant on the area of the world you are in and the regional climate. Where I live the humidity lowers too and we have very dry winters.

Answer 6

humidity is mostly random. It shouldn't change because of the temp.
