What is plane seeding?
Aerial seeding is a technique of sowing seeds by spraying them through aerial mechanical means such as a drone, plane or helicopter. Aerial seeding is considered a broadcast method of seeding. Aerial seeding may quickly and effectively reduce erosion hazards and suppress growth of invasive plant species.
What is the purpose of cloud seeding?
Cloud seeding is a weather modification technique that improves a cloud’s ability to produce rain or snow by artificially adding condensation nuclei to the atmosphere, providing a base for for snowflakes or raindrops to form.
What are the dangers of cloud seeding?
Risks or concerns like unwanted ecological changes, ozone depletion, continued ocean acidification, erratic changes in rainfall patterns, rapid warming if seeding were to be stopped abruptly, airplane effects, to name a few, may just not be bad enough to override the imperative to keep temperatures down.
How Cloud seeding is done?
Cloud seeding involves flying an aircraft to a cloud that has tiny rain droplets present. The aircraft shoots salt flares into the cloud to enhance rainfall.
Is cloud seeding expensive?
In the winter of 2018-2019, water managers in Colorado said their central mountains cloud seeding program produced between 80,000 and 90,000 acre feet of water at a cost of $2.70 per acre foot—a bargain in a region where prices per acre foot can reach $30,000.
Why is cloud seeding done in UAE?
Rain in the UAE Annual precipitation is below 100 millimetres (4 inches) and is concentrated in the winter months. The NCM revealed that they conducted a total of 219 cloud seeding operations across the UAE in the first six months of 2020 to enhance the country’s water supply.
Why does UAE use cloud seeding?
In the UAE, cloud seeding first began as in 2010 as a project by weather authorities to create artificial rain. Forecasters and scientists have estimated that cloud seeding operations can enhance rainfall by as much as 30 to 35 percent in a clear atmosphere, and by up to 10 to 15 percent in a turbid atmosphere.
Does Dubai do cloud seeding?
In the UAE, cloud seeding first began as in 2010 as a project by weather authorities to create artificial rain. The project, which began in July 2010 and cost US$11 million, has been successful in creating rain storms in the Dubai and Abu Dhabi deserts.
Is artificial rain harmful?
Harmful Effects On Environment The scientist added: “The method can lead to acidification of the oceans, ozone layer depletion and an increase in the levels of atmospheric carbon dioxide. Silver is a heavy, toxic metal and it harms the health of plants, humans and animals. Cloud seeding is also a costly method.
