Want this question answered?
It is unknown why salt is actually used for cloud seeding. However, many feel that it is because it is economical and would harm the environment the least.
silver iodide and dry ice
In weatherwhat is used to see cloud patterns and movements?
Yes the word cloud is a noun. It can also be used as a verb.
You may be thinking about the term nucleation or coalescence. Creation of liquid droplets around aerosol particles is called nucleation. The aerosol particles themselves are known as seeds, while the water that form around them are known as droplets. When referring specifically to cloud formation in the atmosphere, the nucleation process is known as coalescence and the seeds can be called cloud condensation nuclei.These seeds can be natural, as in smaller water/ice particles or synthetic chemicals used for cloud seeding, including silver iodide and dry ice.
Cloud seeding uses Silver Iodide to provide nuclei for water to form droplets on. Like most chemicals, Silver Iodide can be harmful if ingested in large quantities, but this requires massive and/or continued exposure. Studies in 1977 and 1981 showed minimal residual traces after cloud seeding. Approximately 50 tons are used each year for this purpose, which is a very small amount in comparison to the total volume of the atmosphere. The effectiveness of cloud seeding is debatable - several organizations have given up on trying to use it in a systematic manner - eg the US National Oceanic and Atmospheric Administration (NOAA) gave up trying to mitigate hurricanes with cloud seeding in 1968 Rumors linking cloud seeding to the chemtrail hoax exist, however barium is not used for cloud seeding.

By attempting to incraese rain
silver iodine
It's called "cloud seeding," and the crystals most often used are silver iodide. The Chinese government plans to use this system to exhaust clouds of their moisture before they drift over the site of the Olympic Games this year.

silver iodide and dry ice
A wide-mouthed funnel and a cylindrical container are used in making an instrument called a rain gauge. In one method of cloud seeding, silver-iodide crystals are used as freezing nuclei.
potassium chloride
Cloud seeding attempts to change the amount or type of precipitation that falls from clouds, by dispersing substances (e.g. microscopic silver iodide crystals, dry ice) into the air that serve as cloud condensation or ice nuclei. The usual intent is to increase precipitation (e.g rain, snow), but hail and fog suppression are also widely practiced in airports. Cloud seeding substances may be dispersed by aircraft or by devices located on the ground (e.g. generators, anti-aircraft guns, rocket launchers). There are still questions as to its actual effectiveness and some of the substances used present possible health hazards.
the use of hygroscopic materials, such as SALT. 1.what is hygroscopic materials? -it is the ability of a substances to attract and hold water molecules from the sourrounding environments.
