These bits of dust and salt are called cloud condensation nuclei.

The second indirect effect is the further knock-on effects of having more cloud condensation nuclei.

Supersaturation of more than 1-2% relative to water is rarely seen in the atmosphere, since cloud condensation nuclei are usually present.

Fog and clouds form through condensation around cloud condensation nuclei.

The number of cloud condensation nuclei in the air can be measured and ranges between around 100 to 1000 per cubic centimetre.

Among these compounds, sulfuric acid has the potential to create new aerosols which act as cloud condensation nuclei.

The effect is expected to be fully reversible, as the cloud condensation nuclei particles precipitate naturally.

By creating cloud condensation nuclei, it might be possible to change the albedo of clouds to make them appear whiter.

Water vapour normally begins to condense on Cloud condensation nuclei such as dust, ice, and salt in order to form clouds.

If a comet was indeed to blame, the action of its aerosols could also have been by the mechanism of cloud condensation nuclei.

Ice nuclei are very rare compared to that cloud condensation nuclei on which liquid droplets form.

Creation of liquid droplets in saturated vapor is also characterized by nucleation (see Cloud condensation nuclei).

Sulfate aerosols can act as cloud condensation nuclei and this leads to greater numbers of smaller droplets of water.

These studies have indicated that the number of cloud condensation nuclei is not very sensitive to the nucleation of aerosols by cosmic rays.

The whitening effect is created by using very small cloud condensation nuclei, which whiten the clouds due to the Twomey effect.

Galactic cosmic rays have been hypothesized to affect formation of clouds through possible effects on production of cloud condensation nuclei.

Sulfates act as cloud condensation nuclei and thus lead to clouds that have more and smaller cloud droplets.

In the atmosphere, condensation produces clouds, fog and precipitation (usually only when facilitated by cloud condensation nuclei).

Cloud Condensation Nuclei (15)

Expanded aerosol systems may include hygroscopic growth instrumentation, size distribution measurements, chemical sampling, and cloud condensation nuclei concentrations.

Eventually the humidity reaches 100 percent, the saturation point, and the moisture condenses onto cloud condensation nuclei, specks of dust in the atmosphere.

As the temperature is cooled to the dewpoint, water vapor condenses upon available cloud condensation nuclei, and forms a cloud.

Some can enter the atmosphere through wave action where they can act as cloud condensation nuclei (CCN).

The heat and airborne debris created by a nuclear explosion can cause rain, debris is thought to do this by acting as Cloud condensation nuclei.

Landsberg's early publications dealt with earthquakes, the impact of weather on aviation, atmospheric suspensions and, most notably, cloud condensation nuclei.
