Cloud condensation nuclei

cloud condensation nuclei counter"(Abbreviated CCN counter.) Any of several devices that measure the number concentration of atmospheric particles upon which water vapor condenses at low values of supersaturation that are equivalent to those that ...

Cloud Condensation Nuclei- small particles in the air on which water vapor condenses and forms cloud droplets.
Cloudy- the state of the sky when 7/10ths or more of the sky is covered by clouds.

Cloud condensation nuclei (CCN) Tiny sold and liquid particles on which water vapor condenses.
Cloud street Clouds aligned in rows due to strong vertical shear in horizontal wind speed or direction. ...

CCN - Cloud Condensation Nuclei. Particles (or aerosols) on which water condenses to form cloud drops.

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

Fog and clouds form through condensation around cloud condensation nuclei. In the absence of nuclei, condensation will only occur at much lower temperatures.

Any substance that has an affinity for water, thereby enhancing condensation of water vapor. Cloud condensation nuclei are typically hygroscopic, ...
