At 100% relative humidity, the air is saturated and is at its dew point. In the absence of a foreign body on which droplets or crystals can nucleate, the relative humidity can exceed 100%, in which case the air is said to be supersaturated. Introduction of some particles or a surface to a body of air above 100% relative humidity will allow ...
The dew point is the temperature when the air will be saturated to 100% humidity, if it could be cooled down that much. When dew point temperatures hit 70 along I-95, for example, that is a humid ...
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls; this is because less vapor is needed to saturate the air. In normal conditions, the dew point temperature will not be greater than the air temperature, since relative humidity typically [5] does not exceed 100%. [6]

A 150-gallon cold tub is about $200 and a wet bulb globe temperature monitor ranges from $100-$750. "Everything that goes into having a sports program has a cost," she said.
A generalized view of the heat index showing how the perception of heat by the human body increases with temperature but more rapidly at higher humidity levels. The heat index of a given combination of temperature and humidity is defined as the dry-bulb temperature which would feel the same if the water vapor pressure were 1.6 kPa. Quoting ...
