Ice nuclei Particles that act as nuclei for the formation of ice crystals in the atmosphere.
Ice pellets See Sleet ...
Freezing Nuclei- Particles suspended in the air around which ice crystals form.
Freezing Rain- Supercooled drops of water that turn to ice when they hit a cold surface.
Front- The boundary between two different air masses.
Freezing Nuclei - Solid pardcles that have a crystal form resembling that of ice; they serve as cores for the formation of ice crystals.
Freezing Rain - See Glaze.
CONDENSATION NUCLEI
A particle upon which condensation of water vapor occurs. It may be either in a solid or liquid state.
Ice-forming nuclei Tiny particles that promote the formation of ice crystals at temperatures well below freezing; include freezing nuclei and deposition nuclei.
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 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 nuclei Tiny particles upon whose surfaces condensation of water vapor begins in the atmosphere.
condensation nuclei—Small particles in the air on which water vapor condenses or sublimates.
See blowing spray as a factor in visibility at sea and as a possible condensation nuclei. SEA SURFACE TEMPERATURE (SST) The temperature of the water's surface.
Many haze formations are caused by the presence of an abundance of condensation nuclei which may grow in size, due to a variety of causes, and become mist, fog, or cloud. Hazemeter Name sometimes given to a transmissometer.
Aerosols are important in the atmosphere as nuclei for the condensation of water droplets and ice crystals, as participants in various chemical cycles, and as absorbers and scatterers of solar radiation, ...
Aitken nucleus"Any one of the many microscopic particles in the atmosphere that serve as condensation nuclei for droplet growth in the large supersaturations (greater than a few hundred percent over water) produced during the rapid, ...
Visibility reduction in fog depends on concentration of cloud condensation nuclei and the resulting distribution of droplet sizes.
There, at temperatures of 15 million degrees Celsius (27 million degrees Fahrenheit) hydrogen atom nuclei, called protons, are fused and become helium atom nuclei.
Condensation Nuclei: Microscopic particles of dust, dirt, CO2, Salt, Etc Smoke which water vapor needs for condensation.
Contrails:Condensation fromed by the exhaust of an aircraft.
CP: Designated letters for a Continental Polar Air Mass: ...
cloud formation: cloud-condensation nuclei, cloud droplets
For condensation to occur at the dew point water vapor needs a surface to condense on.
Of course, in actual practice in the Earth's atmosphere, the ability of water to condense into droplets is generally affected by the presence of hygroscopic dust particles (Cloud Condensation nuclei).
Any substance that has an affinity for water, thereby enhancing condensation of water vapor. Cloud condensation nuclei are typically hygroscopic, ...
CCN - Cloud Condensation Nuclei. Particles (or aerosols) on which water condenses to form cloud drops.
It is created when the temperature and the dew point of the air have become the same, or nearly the same, and sufficient condensation nuclei are present. It is reported as "FG" in an observation and on the METAR.
The precipitation falls to the surface as supercooled rain or drizzle and freezes instantly on contact. The raindrops do not freeze within the cold layer because there are very few ice nuclei in the presence of warmer temperatures.
of a slow-moving anticyclone, and notice lots of thin, white lines criss-crossing the region, which don't appear on the corresponding InfraRed image, these are ships' trails, caused by exhaust particles from the vessel acting as condensation nuclei, ...
contrail: a trail of condensed water vapor formed by jet aircraft flying at high altitudes. This trail is formed by the water vapor added to the air by engine exhaust, as well as particles in the exhaust that act as cloud nuclei.
