Droplets of water deposited when air cools and the water vapor in it condenses.
Water drops deposited by condensation of water vapour from the air, mainly on horizontal surfaces cooled by nocturnal radiation.
Water condensed onto objects at or near the ground, due to the fact that their temperatures have fallen below the dew point temperature of the surrounding air, but not below freezing.
Condensed water vapor collected on surfaces due to the cooling of an air mass to its dew point.
The condensed moisture that forms on cool surfaces.
Water condensed at night from the bottom layer of air.
Condensed atmospheric moisture deposited in small drops on cool surfaces.
Droplets of water condensed from the air onto warmer surfaces.
Water droplets formed by condensation of vapor.
water that has condensed on a cool surface overnight from water vapor in the air; "in the morning the grass was wet with dew"
Water condensed on the ground or objects because the air has dropped below the dewpoint temperature.
When an object or the ground falls in temperature to below that at which the air becomes saturated, the atmospheric humidity condenses on it, forming dew.
Moisture droplets that form on a cool surface.
Condensation of water vapour on a surface whose temperature is reduced by radiational cooling to below the dew-point of the air in contact with it.
Surface moisture on grass leaves. This is usually caused by atmospheric moisture condensing onto leaves and/or by guttation.
Moisture that has condensed on objects near the ground, whose temperatures have fallen to the dew point temperature.
A form of condensation that happens when the overnight temperatures drops to a low enough level.
water drops on an object at or near the ground formed from condensation of water vapor from the surrounding air.
Water which condenses out of the air onto objects near the ground.
Water that has condensed onto objects near the ground when their temperatures have fallen below the dew point of the surface air.
Water that forms on objects close to the ground when its temperature falls below the dew point of the surface air.
Water droplets that form on grass or other objects as a result of condensation of atmospheric moisture as the nighttime temperature falls, resulting in an increase in relative humidity.
Water droplets that form upon surfaces on or near the ground when air is cooled toward its dewpoint.
moisture in the air that condenses on solid surfaces when the air is saturated with water vapor
Atmospheric moisture that condenses after a warm day and appears during the night on cool surfaces as small drops. The cool surfaces cause the water vapor in the air to cool to the point where the water vapor condenses.
water condensed upon the surfaces of objects near the ground when temperatures of the surface air have fallen below the dew point due to cooling during the night but are still above freezing
Atmospheric moisture condensed to liquid on a surface. Cold dew is frost.
Water that condenses onto grass and other objects near the ground.
Moisture that has condensed on objects near the ground, whose temperatures have fallen below the dewpoint temperature.
As the surface of the earth cools at night, warm moist air near the ground is chilled and water vapour in the air condenses into droplets on the grass and other objects. Dew is particularly heavy on clear nights, when the earth cools rapidly. When a blanket of cloud insulates the earth, the cooling rate is slower.
Deposit of water droplets on objects the surface of which is sufficiently cooled, generally by nocturnal radiation, to bring about the direct condensation of the water vapor from the surrounding air.
water vapor that condenses on sold surfaces that have cooled below the condensation point of water
moisture, as in: It was a beautiful spring morning, and the grass sparkled with dew.
Condensation of water vapor on a cooled surface.
Liquid water that has condensed on to objects at or near the Earth's surface.
Water condensed onto grass and other objects near the ground, the temperatures of which have fallen below the dewpoint of the surface air due to radiational cooling during the night, but are still above freezing; hoarfrost may form if the dewpoint is below freezing ( see frost point). If the temperature falls below freezing after dew has formed, the frozen dew is known as white dew. The conditions favorable to dew formation are 1) a radiating surface, well insulated from the heat supply of the soil, on which vapor may condense; 2) a clear, still atmosphere with low specific humidity in all but the surface layers, to permit sufficient effective terrestrial radiation to cool the surface; and 3) high relative humidity in the surface air layers, or an adjacent source of moisture such as a lake. Dew plays an important role in the propagation of certain plant pathogens, such as late potato blight, which require dew-covered leaves from certain stages of sporulation. Dew is responsible for the optical effect known as the heiligenschein.
Condensation in the form of small water drops that forms on grass and other small objects near the ground when the temperature has fallen to the dew point, generally during the nighttime hours.
1. Moisture, which condenses after a warm day and appears during the night in little drops on cool surface. 2. Anything regarded as refreshing.
Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening. As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that of which it can evaporate, resulting in the formation of water droplets.
