Smoke compositions can be also used for weather modification, namely cloud seeding, to provide cloud condensation nuclei for the moisture to precipitate.
22.
The concept of cloud condensation nuclei is used in cloud seeding, that tries to encourage rainfall by seeding the air with condensation nuclei.
23.
Supersaturation of more than 1 2 % relative to water is rarely seen in the atmosphere, since cloud condensation nuclei are usually present.
24.
Sulfate aerosol influences the Earth's radiation budget by scattering and absorption of shortwave and long-wave radiation, and by acting as cloud condensation nuclei.
25.
Like other precipitation, hail forms in storm clouds when supercooled water droplets freeze on contact with condensation nuclei, such as dust or dirt.
26.
The concept of cloud condensation nuclei is used in cloud seeding, that tries to encourage rainfall by seeding the air with condensation nuclei.
27.
Under this scenario, deprived of nutrients, marine phytoplankton would decline, as would sulfate cloud condensation nuclei, and the high albedo associated with low clouds.
28.
Increasing amounts of ice and condensation nuclei would be need to be high for the polar stratospheric cloud to sustain itself and eventually expand.
29.
However, employment of the condensation nuclei counter ( CNC ) technique would allow a higher detection sensitivity in particle sizes down to nanometre range.
30.
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.
