Sentences with phrase «nucleate cloud»

Coatings with soluble substances, such as sulphate or nitrate, will change the ability of mineral dust aerosols to nucleate cloud droplets (Levin et al., 1996; Section 7.5.2.1).

If sulfate aerosols nucleate cloud drops, resulting in a greater number of smaller droplets rather than a few large ones, this will further increase scattering and cooling.

The results showed lead in about half of the particles that nucleate clouds.

Increased biomass can lead to increased emissions of biogases such as dimethyl sulfide and isoprene, which when oxidized in the atmospheric form sulphate and organic aerosols that can nucleate clouds, increasing cloud cover and planetary albedo — the CLAW Hypothesis.

Not exact matches

These clouds obviously contain something that efficiently nucleates ice at those much warmer temperatures.

Dozens of states and countries run cloud - seeding programs using artificial ice - nucleating compounds.

«We found that exposing particles to sunlight makes the particles increasingly more oxidized and acidic, which in turn makes it easier for such particles to nucleate water and make cloud droplets,» said Professor Sergey Nizkorodov, a physical chemist at UCI who led the study.

Ice - nucleating bacteria — which have been referred to as «rain - making bacteria» — may be significant triggers of freezing in clouds and influence the water cycle.

This was an experiment which aimed to test the hypothesis that cloud seeding with silver iodide could suppress hail by creating an excess of nucleating embryos that would compete for the available cloud water (and thus keep all the hydrometeors smaller)-- more precipitation, in fewer big «globs» of hail.

In a process called cloud seeding, silver iodide, with effective ice - nucleating temperatures of less than − 4 °C, has been used for years in attempts to convert supercooled water to ice crystals in regions with a scarcity of natural ice nuclei.

Some of the work at CERN seemed to say that cosmic rays nucleate very small droplets that do not increase to cloud size... Anyway, some of us follow GCR for reason of climate amplifications and even Ozone hole development.
