Artificial cloud


An artificial cloud is a cloud induced by human activity. Usually the artificial cloud is formed by providing particles for condensate to form around.[1] Various methods have been proposed for creating and utilizing this weather phenomenon and artificial clouds have also been created to carry out various studies. Russian scientists have been studying artificial clouds for more than 50 years.[2] But by far the greatest number of artificial clouds are airplane contrails (condensation trails) and rocket trails.[3][4]

Experiments

NASA studied inducing high altitude noctilucent clouds in 1960[5] 2009.[6][7] In 1984 satellites from three nations took part in an artificial cloud experiment as part of a study of solar winds and comets.[8] A European satellite released and ignited barium and copper oxide 43,000 miles in space to create a 2,000 mile mauve and green plume visible for 22 minutes. It was part of a study of magnetic and electric fields.[9]

Ideas

Plans to create artificial clouds over soccer tournaments in the Middle East were suggested in 2011 as a way to help shade and cool down Qatar's 2022 FIFA World Cup.[10]
