Water Transport through the air
Animation by: Bramer
In the hydrologic cycle, transport is the movement of water through the atmosphere, specifically from over the oceans to over land.
Water sky The dark appearance of the underside of a cloud layer when it is over a surface of open water. It is darker than land sky, and much darker than ice blink or snow blink.
Water vapor will only condense onto another surface when that surface is cooler than the temperature of the water vapor, or when the water vapor equilibrium in air has been exceeded.
Water is one element in the atmosphere which occurs in all three states at one time:
**Solid...Liquid...Gas**
In the liquid state we see water in the form of: ...
Water vapour pressure is the atmospheric pressure which is exerted by water vapour (water in its gaseous state). It is one way of measuring the humidity of the air.

Waterspout: A violently rotating column of air, usually a pendant to a cumulus or cumulonimbus cloud, over a body of water with its circulation reaching the water.
water vapor"(Also called aqueous vapor, moisture.) Water substance in vapor form; one of the most important of all constituents of the atmosphere.
Waterspout - In general, a tornado occurring over water. Specifically, it normally refers to a small, relatively weak rotating column of air over water beneath a Cb or towering cumulus cloud.

Water vapour
Water vapour is gaseous water present in the atmosphere.
WATER
Refers to the chemical compound, H2O, as well as its liquid form. At atmospheric temperatures and pressures, it can exist in all three phases: solid (ice), liquid (water), and gaseous (water vapor).

The alteration of the constituents of a body of water by man to such a degree that the water loses its value as a natural resource.
WATERSPOUT: A column of rotating air over a body of water (ie. a tornado over the water).

Water- a transparent, odorless, tasteless liquid; composed of hydrogen and oxygen.
Waterspout- a column of rapidly spiraling air that develops over warm, usually shallow, water in seas or large lakes.
Waterspout: A type of whirlwind that forms underneath cumulus clouds over a large body of water.
Watt: A unit of power or energy per unit time.
Wavelength: The distance between one crest of a wave and another.
Water Spout
A spout occurring over water; this behavior is characterized by a tendency to dissipate upon reaching shore.
Water Table
The surface separating the upper layer of non-saturated soil and the lower layer of saturated soil.
Water vapor Water in a vapor (gaseous) form. Also called moisture.
Wave cyclone An extratropical cyclone that forms and moves along a front. The circulation of winds about the cy clone tends to produce a wavelike deformation on the front.
Water budget Balance sheet for the inputs and outputs of water to and from the various global water reservoirs.
waterspout—See tornado.
water vapor—Water in the invisible gaseous form.
Waterspout- A rapidly rotating column of air extending from a cumulonimbus cloud with a circulation that reaches the surface of the water, (i.e. a tornado over water).
Water Vapor (aka moisture) Water in a gaseous form.
Wave 1. In electricity, a periodic variation of an electric current or voltage. 2.
Water Vapor
Water in a gaseous (vapor) form especially when below boiling temperature and diffused.

Tailwater Height: Height of water immediately downstream of the dam. (Various datums may be used.)

Headwater Basin
In hydrologic terms, a basin at the headwaters of a river. All discharge of the river at this point is developed within the basin.

SALT WATER The water of the ocean, distinguished from fresh water by its appreciable salinity.
"The Water Tower of Europe" "The water tower of Europe" is a phrase used to describe the country of Switzerland, specifically the Swiss Alps which serve as a source region for many of Europe's great rivers.
Supercooled water - Water that is below the freezing temperature but is still in liquid form.
Waterspout: Phenomenon similar to the tornado that occurs over the sea.
Weakening: In synoptic meteorology, the weakening of a high- pressure center means a decrease in its central pressure in time.
Water sufficiently deep that surface waves are little affected by the ocean bottom. Generally, water deeper than one-half the surface wave length is considered deepwater.

Water vapor- Water in the form of a gas.
Weather- The condition of Earth's atmosphere at a particular time and place.
Wind-chill factor- Increased cooling caused by the wind.
Water that condenses onto grass and other objects near the ground.
Dew Point
The temperature at which air becomes saturated with water vapour. I.e. the relative humidity is 100 %.
Waterspout- A tornado-like formation over water, usually much smaller and less vigorous than a true tornado.
Water Vapor - It's a gas in the atmosphere. There is very little of it in the air. Water vapor is only 1 to 4% of the atmosphere, but without it we would have no clouds, rain, or snow.
