  • The second indirect effect is the further knock-on effects of having more cloud condensation nuclei.
  • Some can enter the atmosphere through wave action where they can act as cloud condensation nuclei (CCN).
  • Among these compounds, sulfuric acid has the potential to create new aerosols which act as cloud condensation nuclei.
  • By creating cloud condensation nuclei, it might be possible to change the albedo of clouds to make them appear whiter.
  • Sulfates act as cloud condensation nuclei and thus lead to clouds that have more and smaller cloud droplets.
  • Ice nuclei are very rare compared to that cloud condensation nuclei on which liquid droplets form.
  • Small particles of sea salt are the dominant cloud condensation nuclei well out at sea, which allow the formation of clouds in otherwise non-polluted air.
  • Sulfate aerosols can act as cloud condensation nuclei and this leads to greater numbers of smaller droplets of water.
  • If a comet was indeed to blame, the action of its aerosols could also have been by the mechanism of cloud condensation nuclei.
  • Our understanding of what particles make efficient ice nuclei is poor - what we do know is they are very rare compared to that cloud condensation nuclei on which liquid droplets form.
  • Fog and clouds form through condensation around cloud condensation nuclei.
  • The whitening effect is created by using very small cloud condensation nuclei, which whiten the clouds due to the Twomey effect.
  • The effect is expected to be fully reversible, as the cloud condensation nuclei particles precipitate naturally.
  • The particles rose to a maximum of, but were scavenged by cloud condensation nuclei from the atmosphere relatively quickly.
  • These aerosols act as cloud condensation nuclei and increase cloud droplet number, which in turn elevate the liquid water content of clouds and cloud area.
  • 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.
  • Supersaturation of more than 1-2% relative to water is rarely seen in the atmosphere, since cloud condensation nuclei are usually present.
  • Alternatively it could cause it to last much shorter, as there would be more water vapor for the rocky aerosol particles to form cloud condensation nuclei.
  • Broadly speaking, the marine environment has a deficit of cloud condensation nuclei due to lower levels of dust and pollution at sea, so this technique is more effective over the ocean than over land.
  • Cloud droplets form onto pre-existing aerosol particles, known as cloud condensation nuclei (CCN).
