What is the meaning of DEW POINT?
The dew point temperature is defined as the temperature at which the air becomes saturated with water vapor when the air is cooled by removing sensible heat. It is very important in meteorology because it is directly related to the amount of water vapor in the air and it can be used to determine other variables (e.g., vapor pressure, relative humidity, wet bulb temperature, and vapor pressure deficit) that are often used in agriculture. In addition, the dew point measured during nighttime is often a good first guess for the next morning’s minimum temperature. Consequently, it is extremely important for freeze protection of crops.
