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.
Not exact matches
At this
temperature and density elements can
nucleate and form solid particles.
These clouds obviously contain something that efficiently
nucleates ice at those much warmer
temperatures.
For bulk water samples, these conditions are described as «no man's land,» because ice
nucleates before such
temperatures can be reached.
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.
