If you know the temperature and moisture content of the air, you can determine the minimum temperature of surfaces to prevent the condensation formation on them. Whether the condensation occurs depends on how much water vapor is contained in the air and how far the air is cooled down.
Also on cold water pipes that lead through warmer areas and on tiles, windows and mirrors in bathrooms, condensation is often visible after showering. For example, the lenses of the glasses can fog up when you come from the cold into the heated rooms. It is not necessary to cool down the entire air, it is sufficient that the air passes by small cold surfaces. Since warm air can absorb more moisture than cold air, condensation or condensation water is formed when the humid air is cooled down. Other names for this liquid formed from the humidity in the air are condensate or condensation water. Condensation water, on the other hand, is the water that settles as the liquid on the inner side of tents or on cool glass or metal. Dew drops are the visible drops of water that can often be seen on the grass in the morning, even when it has not rained. On the other hand, the water that has become liquid from the gaseous phase is also called dew or condensation. The term thawing stands for the transition from the solid to the liquid phase. For the transition from one state to the other, there are the generally used terms freezing, thawing, evaporation, evaporation. The temperature of the metal at this state represents the dew point temperature.Įveryone knows the three states of aggregation of water: solid, liquid and gaseous. One possibility to measure the dew point temperature is to let metal cool down until its surface is steamed with water vapour. When the dew point temperature and the air temperature are known, meteorological phenomena like fog, dew or rain can be predicted in many cases. With a dewpoint meter, you can determine the dew point temperature and the air temperature, so that you can always keep the environmental circumstances in mind and prevent undesirable condensation which might cause damage to electrical devices or injuries.Ī dew point thermometer can also be used to forecast the weather to a certain degree. The dew point temperature does not depend on the current temperature. If the air temperature falls below the dew point temperature, the water begins to condense. The dew point temperature is the temperature (at a specific atmospheric pressure) at which the air is completely saturated with water.

Raphael Romero Ruiz, The Arizona Republic, The dew point statewide is expected to climb into the low to mid-60s overnight. Julia Musto, Fox News, 15 July 2022 Before the weather service established these dates, the start of the season was signaled by three consecutive days of average dew point temperatures of 55 degrees or higher. Hartford Courant, 28 July 2022 The National Weather Service's office in Phoenix said that showers moving through the metro area had brought the low temperatures down and pushed the dew point above 70 degrees Fahrenheit. 2021 There will be comfortable humidity on Saturday, then moderate humidity Sunday as the dew point climbs into the lower 60s. Matthew Cappucci, Washington Post, 7 July 2022 There will be a break in the humidity Saturday, then the dew point will be climbing through the 60s on Sunday.Ĭ, 28 Aug. 2022 In Albuquerque, the summertime average is 47 degrees for the dew point. 2022 While temperatures were in the lower 80s, the dew point dropped into the lower 40s in the afternoon and that led to a very comfortable evening.
Gary Robbins, San Diego Union-Tribune, 19 Aug. Recent Examples on the Web The dew point will be in the 65 degree to 68 degree range during that period.
