The UAE is located in one of the hottest and driest regions on Earth. For more than 23 years, the country has been making efforts to increase rainfall and mine clouds through cloud seeding techniques using airplanes. Impacts of climate change, including rising global temperatures, are affecting the Gulf region and increasing population is contributing to the depletion of water resources in the country. The country meets its daily needs by purifying and supplying sea water.
The world’s climate guide, Climates to Travel, points out that annual rainfall in the UAE is below 100mm almost everywhere. Mostly there is drizzle. Heavy rainfall is rare.
Artificial means are used to reduce rainfall as well as to make it rain. This is made possible by driving away the rain clouds. This was done to avoid rain in parts of the stadium on the day of the Melbourne Olympics final. Residents of Jeddah had approached the court questioning how the rain clouds were chased away from time to time to prevent rain in Jeddah
Scientists in the UAE are using different methods for cloud seeding missions. Chemicals are sprayed with jets to stimulate and accelerate the condensation process to form larger raindrops.
Nanoparticles of salt are released into the clouds to produce droplets large enough to fall as rain. Hygroscopic salt flames are shot with special planes. Cloud seeding technology works by introducing seeding agents in the lower part of clouds with favorable updrafts. These agents are carried to the top of the clouds and increase the microphysical processes such as condensation and coalescence and increase the size of the droplets.
