Cloud Seeding Methods
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. The government even guaranteed clear skies for the event -- a promise it managed to deliver on. The feat only took the launch of 1,104 rain dispersal rockets from 21 sites in the city to pull off [source: O'Neill].
Even in areas with very low humidity, there's at least some water in the sky and clouds. A rainstorm happens after moisture collects around naturally occurring particles in the air, causing the air to reach a level of saturation at which point it can no longer hold in that moisture. Cloud seeding essentially helps that process along, providing additional "nuclei" around which water condenses. These nuclei can be salts, calcium chloride, dry ice or silver iodide, which the Chinese use. Silver iodide is effective because its form is similar to ice crystals. Calcium chloride is often used in warm or tropical areas.
Saudi uses 11 planes to bring rain to Riyadh
Saudi Arabia has started the fourth phase of its program to extract rain from clouds, part of a project started five months ago to secure more water resources in the kingdom, recent press reports said.
The head of the Meteorological and Environmental Protection Administration, Saleh al-Shahri, said 11 planes are being used in the current phase, together with a high-tech network of mobile cloud physics radars, a communication and satellite network, and experts from various Saudi universities and research centers.
Shahri told Saudi newspaper Al-Riyadh that the program is part of the kingdom's ongoing efforts to counter the scarcity of water, especially since ground water is subject to depletion.
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.
Dude its just my theoryWas there also cloud seeding in Asia affecting Somaliland in 1911-12, 1914, 1918, 1925, 1927-28, 1933-34, 1938, 1943, 1950-51, 1955, 1959, 1968-69 and 1973-74?
a more acceptable theory is trees!! you cut trees and rain hardly come.it is a desert nation,somalia is desert by 2/3,that is a huge desert.
Defrostation is the leading cause of droughts because it's a direct impact to climate change! Here's a great example between Haiti and Dominican Republic and according to scientists Haiti has more droughts in comparison to its neighbors and most of the Caribbean islands. It's a known fact cutting down forests and trees will release stored carbon dioxide, which in return will trap heat and contribute to further atmospheric warming. What we need to do is plant more trees and substitute charcoal with something more substainable, considering charcoal is probably the only source of cooking for reer miyiga in their invietible search for better pasture lands for their cattle. The sooner we can educate reer miyiga the less likely they will continue to contribute to this destruction.
That's actually false, removing the livestock would destroy the environment even faster.We need more trees cover. Also the land can't support 25 million animals thats crazy. Imagine ten thousand head of goats and their hooves on the ground effect. Their hooves alone kills wide area.
Now days there are more goats then sheep , a half century ago there were maybe 10% goats for every 100 head , now its almost 40% sheep and 60% goats. Goats are notorious erosion agents.
