Condensation
The transformation of water from a gas into a liquid, and the processes that lead to condensation.
Transport
The movement of water through the atmosphere.


Condensation nuclei - Tiny particles invisible to the human eye, such as dust, dirt, an pollutants, provide surfaces on which water molecules can condense and gather into water droplets ...

CONDENSATION PRESSURE DEFICIT (COND PRES DEF)- On an isentropic chart (a layer of constant potential temperature), condensation pressure deficit represents the amount of lift, expressed in millibars, needed to saturate an air parcel.

Condensation - The process by which water vapour becomes a liquid. Conduction - The transfer of heat by molecular activity from one substance to another, or through a substance. Transfer is always from warmer to colder regions.

Condensation - The change of state from vapor to liquid. The process releases latent heat.
Conditional instability - A type of atmospheric instability where the air is stable if it is dry, and unstable if it is saturated.

CONDENSATION: The process of gas changing to liquid.
CONTINENTAL AIR MASS: A dry air mass originating over a large land area.

condensation: when a vapor becomes a liquid due to some change. Occurs often when the temperature becomes cooler, the humidity becomes greater, or the air pressure changes.

Condensation Process by which water changes phase from a vapor to a liquid.
Condensation nuclei Small particles in the atmosphere that serve as the core of tiny condensing cloud droplets. These may be dust, salt, or other material.

Condensation- the occurrence of vapor transforming into a liquid.
Conduction- the transfer of heat between bodies that are in contact.

evaporation—The change of liquid water to water vapor.
freezing—The change of liquid water to ice.

CONDENSATION FUNNEL A funnel-shaped cloud consisting of condensed water drops that has possible rotation.
CONDENSATION NUCLEI A particle upon which condensation of water vapor occurs. It may be either in a solid or liquid state.

Condensation- The process by which water vapor becomes a liquid; the opposite of evaporation, which is the conversion of liquid to vapor.
Condensation Nuclei- Small particles in the air around which water vapor condenses.

Condensation
In general, the physical process by which a vapor becomes a liquid or solid; the opposite of evaporation, although on the molecular scale, both processes are always occurring.
Condensation Funnel ...

CONDENSATION
The process by which water vapor undergoes a change in state from a gas to a liquid. It is the opposite physical process of evaporation.
CONDENSATION FUNNEL ...

Condensation Change of a substance to a denser form, such as gas to a liquid. The opposite of evaporation.

Cool Condensation
Clouds are water. As you probably know, we can find water in three forms: liquid, solid and gas. Water as a gas is called water vapor. Clouds form when water vapor turns back into liquid water droplets.

Lifting Condensation Level (LCL) It is the height at which a parcel of air becomes saturated when lifted dry-adiabatically.
Lightning A sudden visible flash of energy and light caused by an electrical discharges from thunderstorms.

Condensation
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.

Condensation of atmospheric moisture occurs when:
the volume of air remains constant but temperature is reduced to dewpoint; e.g. contact cooling and mixing of different layers
the volume of an air parcel is increased through adiabatic expansion ...

Condensation: Process of transformation of water vapor into liquid water.
Continuous Precipitation: Term applied to precipitation caused by stratiform clouds which persists for one hour or longer.

condensation- formation of liquid water from vapor, either around a small particle or on a solid surface. See dew point, evaporation.

Condensation- The change of vapor to liquid.
Condensation Nuclei- Small particles in the air around which water vapor condenses.
Conduction- The transfer of heat by molecular action within a substance or when two substances are in direct contact.

CONDENSATION - A change of state of water from a gas (water vapor) to a liquid.

Condensation is the general term for the change of phase from a vapour to a liquid or directly to ice. It will occur if a saturated region is cooled and there is a surface on which condensation can begin.

CONDENSATION FUNNEL - The visible pendant cloud of a tornado. This is caused by air pressure and wind speed changes associated with vortex allowing the vapor in the air to condense into water droplets.

A condensation funnel extending from the base of a towering cumulus or Cb, associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado).

Cause: Condensation occuring in a thin layer of air immediately above the ground.
Associated Weather: None ...

(2) Condensation releases heat and the further lifted air will cool somewhat slower now, lets say at a typical rate between 0.5 and 0.65C/100m. This is called the wet or saturated adiabatic lapse rate.

Lifting Condensation Level - the level at which a parcel of moist air becomes saturated when it is lifted dry adiabatically.LDSLightning Detection SystemLDTLocal Daylight Time.

Xenia, OH on 3 April 1974, which was rated F5 but appeared only as a series of suction vortices without a central condensation funnel).

accumulation (glacial) All processes, which include snowfall, condensation, avalanching, snow transport by wind, and freezing of liquid water, that add snow or ice to a glacier, floating ice, or snow cover.

The heating occurs due to the release of the latent heat of condensation, caused by the above-normal upward movement of water vapor into the upper atmosphere.

Visibility reduction in fog depends on concentration of cloud condensation nuclei and the resulting distribution of droplet sizes.

Wedge (or Wedge Tornado): Slang for a large tornado with a condensation funnel that is at least as wide (horizontally) at the ground as it is tall (vertically) from the ground to cloud base.

As warm air rises it may cool and reach the saturation point where condensation occurs. This process releases energy to the atmosphere (at the rate of 585 calories per gram of water).

A rotating "cloud" of dust or debris, near or on the ground, often appearing beneath a condensation funnel and surrounding the base of a tornado.

cloud formation: cloud-condensation nuclei, cloud droplets
For condensation to occur at the dew point water vapor needs a surface to condense on.

However, it will be obvious from the description (above) relating to condensation trails, that the heat outflow must markedly outweigh the injection of water vapour from the spent fuel, and the phenomenon is rare.

1650: Ferdinand II, the Grand Duke of Tuscany, invented the condensation hygrometer.
1769: German Lambert made a hygrometer.
1783: Swiss H.B. Saussure invented the hair hygrometer.

A condensation funnel does not need to reach to the ground for a tornado to be present; a debris cloud beneath a thunderstorm is all that is needed to confirm the presence of a tornado, even in the total absence of a condensation funnel.

Any substance that has an affinity for water, thereby enhancing condensation of water vapor.

It is the condensation trail of ice crystals left behind by the exhaust of a flying jet aircraft. These aircraft fly 8 to 12 kilometres above the ground pulling in very cold, dry air and spewing out hot, water-filled exhaust.

Heat is added to the air through condensation of water vapour (latent heat) thus reducing the rate at which the air cools.

Latent heat - heat given off by condensation, or absorbed by evaporation, of water.
Lightning - a giant electrical spark jumping between clouds or between a cloud and the ground.

The term implies both poleward displacement of the cyclone and the conversion of the cyclone's primary energy source from the release of latent heat of condensation to baroclinic (the temperature contrast between warm and cold air masses) processes.

Relief rainfall Formed when air is forced to rise over relief features such as hills or mountains. Cooling and condensation occurs as the air rises.

Hurricanes are driven by the heat released by condensation of water vapour, and depend on a warm ocean surface to give them lots of water vapor.
