When cloud seeding, increased snowfall takes place when temperatures within the clouds are between −4 and 19 °F (−20 and −7 °C). Present-day geoengineering proposals have focused on the global scale, particularly as evidence has mounted of increasing atmospheric CO 2 concentrations and thus the prospect of global warming.Two fundamentally different approaches to the problem of global climate … Another useful application for cloud seeding is the treatment of ground-based clouds, also known as fog. Schaefer discovered the principle of cloud seeding in July 1946 through a series of serendipitous events. Cloud seeding, a form of weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei. These materials then alter microphysical processes within the cloud, for example by providing additional condensation / ice nuclei or altering relative humidity by … The goal of cloud seeding is to alter the natural development of the cloud to enhance precipitation, suppress hail, dissipate fog, or reduce lightning. Cloud seeding is an artificial way of inducing moisture in the clouds to cause rainfall. This can produce ice crystals at higher temperatures than silver iodide. 2. You consent to our cookies if you continue to use our website. For the "cold rain" process, silver iodide can be used as a nuclei because its structure is very similar to ice crystals. Cloud seeding by silver iodide is done either from ground generators or form airborne generators. Liquid propane, which expands into a gas, has also been used. During the 1930s, the Bergeron–Findeisen process theorized that supercooled water droplets present while ice crystals are released into rain clouds would cause rain. List of Pros of Cloud Seeding. Large hydroscopic particles (salt powders and hygroscopic flare-produced particles; see image below) are injected into a cloud to increase the concentration of “collector drops” that can grow into raindrops by Cloud seeding is a form of weather modification that enhances the amount of precipitation in clouds. Louis Gathmann in 1891 suggested shooting liquid carbon dioxide into rain clouds to cause them to rain. Cloud seeding is a form of weather modification, a way of changing the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. Cloud seeding mechanism depends on the difference in vapour pressure over ice and supercooled water at the same temperature.

When people speak of weather control and cloud seeding, many minds turn to conspiracies and dark corners of the world’s governments looking to cripple their enemies with a flood, hurricane, or both. Cloud Seeding is a method of weather modification: Seeding agents are dispersed into clouds in a controlled manner. Types of Cloud Seeding Hygroscopic seeding is used in warm or mixed-phase clouds. 1. Cloud seeding works on a regional scale, seeking to influence weather systems for the benefit of agriculture. It creates rain. The full impact of cloud seeding is still not fully known, but it is helpful to what its pros and cons are so far. Cloud seeding is a form of weather modification that enhances the amount of precipitation in clouds. The Beijing Weather Modification Office spent a lot of time researching how to prevent rain in the city during the Aug. 8 opening ceremony of the 2008 Summer Olympics. Cloud seeding is thought to increase the number of these nuclei available to take greater advantage of the moisture in the cloud and form raindrops that otherwise would not have formed. Supercooled fogs, comprised of water droplets at temperatures cold enough to permit ice development, can easily be cleared by glaciogenic seeding. It makes all areas more hospitable. Cloud seeding involves the addition of aerosol, such as silver iodide aerosol, that modifies the phase and size distribution of hydrometeors. However, all these are not as effective as silver iodide. Cloud seeding by silver iodide is done either from ground generators or from airborne generators. 1. It creates rain. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. The usual intent is to increase precipitation, and, in … Types of Cloud Seeding – The most common chemicals used for cloud seeding include silver iodide, potassium iodide, and dry ice (solid carbon dioxide). And, as limited as it is, there is some documentation showing that government departments have at least looked at the possibility of such environmentally orientated weapons. Substances other than silver iodide as artificial nuclei are lead iodide, cupric sulphide, cupric oxide, ammonium fluoride, cadmium iodide and iodine. The Le_Meridian Funding Service went above and beyond their requirements to assist me with my loan which i used expand my pharmacy business,They were friendly, professional, and absolute gems to work with.I will recommend  anyone looking for loan to contact. Here in the UAE, Beechcraft C90 King Air planes are deployed to spray the atmosphere with salt crystals mixed with potassium, sodium chloride and magnesium. While researching aircraft icing, General Electric (GE)'s Vincent Schaefer and Irving Langmuirconfirmed the theory.

This means cloud seeding can get rid of famine in the future. The introduction of a substance such as silver iodide, which has a crystalline structure similar to that of ice, will induce freezing nucleation. It is a form of weather modification. One big benefit of cloud seeding is being able to create rain in regions that are most affected by droughts, lessening the impact of the harsh climate.
