Sentences with phrase «of nucleating»

Vonnegut went on to invent what amounted to a nucleating machine: He dissolved silver iodide in acetone, sprayed the solution through a nozzle to make droplets, and then literally burned the droplets, producing trillions of nuclei; under the right conditions, each could form the core of a drop of water or flake of snow.

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.

In addition, many non-sulfur-based biogenic materials of the terrestrial environment play major roles as water - and ice - nucleating aerosols; and the airborne presence of these materials should also be enhanced by rising levels of atmospheric CO2.

Suppose the polywater scare had happened now, perhaps we would have had an IPPC set up to make recommendations as to how to avoid a possible catastrophe involving a small quantity of polywater entering the sea and nucleating the rest of it to convert to polywater — like a wet windscreen on a cold winter's day.

When moisture laden storms are saturated with artificial / chemical ice nucleating elements (due to the destructive attempt by the climate engineers to temporarily cool - down ground temperatures on the ground), storms that would have been a deluge of rain become unprecedented onslaughts of frozen precipitation.

Well, to make it work, the mechanism needs clean air (which you always had over at least parts of the oceans) and nucleating aerosols (e.g., as you get from DMS, which is primarily formed by phytoplankton which exists for a loooooong while), so yes, it is reasonable that the mechanism has been operational, though quantitatively it may have changed somewhat.

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.

I, like you, am very skeptical of any attempt to remove some particular «natural signal» from a coupled nonlinear chaotic system with gazillions of feedbacks known and unknown and (mostly) transient, fluctuations that happened to nucleate at some particular point and grow.

'' The freezing / melting point of pure water is 0C» Sorry if someone else has already raised this point, but when I lived in Alberta it was repeatedly inculcated that without a nucleating agent, pure water did not freeze until about -39 C. Maybe this is only of biological importance (0C melting point is ok), but I think you need to be more precise.

We can barely predict in the roughest of terms how many of the waves are likely to nucleate into storms (not all of which start off of Africa — sometimes they nucleate in the Gulf of Mexico, sometimes in the Caribbean, sometimes in the middle of the Atlantic), and the distribution of energy among those storms.
