The Dew Point.
Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
The relative humidity of the air is a measure of how much moisture is in the air compared to the maximum amount of moisture the air can hold at a given temperature. It is expressed as a percentage and indicates how close the air is to reaching its saturation point.
dew point
The closer the ambient and dew point temperatures get, the more moisture is in the air.
Yes! In fact, the air temperature and dewpoint should be exactly the same during heavy fog.
The temperature in which air is saturated and condensation can occur is the "dew point." It has no specific temperature but it occurs when the air is saturated. The air is saturated when it has a relative humidity of 100 percent, or if i cools down to its dew point.
The relationship that you expect to find between the air temperature and dew point temperature at ground level if the area is covered by fog is the temperatures of th air and the dew point would be very close in value.

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.
Yes.
When both come closer,relative humidity increases;When they are almost equal,condensation water vapour begins.
The Dew Point.
Dew point is the temperature at which air becomes saturated.
The temperature to which air must be cooled to reach saturation is called the dew point.
Yes. Below the freezing point the relative humidity will indicate how close the moisture in the air is to depositing and forming frost or snow.
