A relative humidity of 100% means that the air can't hold any more water vapor. More evaporation takes place when the air is dry because dry air has a higher capacity than moist air to absorb additional moisture. When the dewpoint and temperature are the same, the relative humidity is 100 percent. For example, warm air can hold more water vapor, or moisture, than cold air. In colder months, the optimal indoor humidity range is 30 to 40 percent. See more current weather. Dew point is an absolute measure and helps us understand how muggy and humid it feels outside.

Simple explanations of weather elements should have been a part of the app's initial design. Little cloud droplets come together with other small droplets to form large droplets. What is the dew point temperature? Humidity depends on the temperature and pressure of the system of interest. The Earth then radiates energy away, but some of it is trapped by greenhouse gases on its way out, adding extra warmth. We know that a sponge saturated with a half mug of water has 50% humidity, on increasing the size of the sponge (increasing the temperature) without adding water further, the relative humidity decreases because the sponge becomes bigger and is capable to take on water vapour; however, the amount of water remains the same. We define specific humidity as the mass of water vapour present in a given unit mass of moist air. Knowing exactly how much water is in the air in specific regions is essential for accurate weather forecasts. Similar to high humidity levels, low humidity levels can lead to health issues, discomfort, and problems in your home as well.
