condensation
the physical process by which a vapor becomes a liquid or solid; the opposite of evaporation; in meteorological usage, this term is applied only to transformation from vapor to liquid; ...


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.
Convection- the transfer of heat within a gas or liquid by their movement.

Condensation - The physical process by which water vapor in the atmosphere changes to liquid in the form of dew, fog or cloud; the opposite of evaporation.
CONUS - Continental United States ...

Condensation Funnel - A funnel-shaped cloud associated with rotation and consisting of condensed water droplets (as opposed to smoke, dust, debris, etc.). Compare with debris cloud.

Condensation Nuclei: Liquid or solid particles, such as those in smoke or dust, that provide a surface upon which water vapour can condense into cloud droplets or form ice crystals.

Condensation - The change of state from a gas to a liquid.
Condensation - Nuclei Microscopic particles that serve as surfaces on which water vapor condenses.

Condensation
The physical process by which water vapor is transformed into dew, fog, or cloud droplets.
Continental Air
Mass of air which remains over a continent for several days and which, therefore, has a fairly low moisture content.

Condensation level The level above the surface marking the base of a cumuliform cloud.
Condensation nuclei Tiny particles upon whose surfaces condensation of water vapor begins in the atmosphere.

Condensation - The process by which water vapor becomes a liquid.
Conditional stability - Property of an ambient air layer that is stable for unsaturated (clear) air parcels and unstable for saturated (cloudy) air parcels.

condensation—The change of water vapor to liquid water.
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
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.

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: 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.
