Said another way, the dew point temperature is the temperature at which the air must become cooled in order to become completely saturated with water vapor. If the air tem - perature is equal to or below th The dew point temperature can never be higher than the air temperature. Dew point temperature (com - monly referred to as 'dew point' or 'dewpoint') is the temperature at which water vapor in any gas at constant pressure begins to con - dense into liquid water at the same rate as it evaporates. Dew point temperature - What does it mean and how can itĪ. A high dew point means that the air is unstable and that. A very high dew point can indicate severe weather. That means that the dew point temperature is always less than the air. Dew point depression is the difference between the dry bulb temperature and dew point temperature of air at any point The dew point is useful in weather forecasts for a number of reasons: Air temperature must fall to the dew point. It is an industrial de facto to call these types of low humidity instruments as dew point meters Dew point temperature is defined as, the temperature of air recorded by a thermometer, when the moisture (water vapour) present in it begins to condense. It is often used to measure dryness in applications such as plastics and compressed-air drying, where the relative humidity is typically below 10%RH. Dew point temperature is a useful parameter in many industrial humidity applications.
