Last June Metro Systems built five ionising sites each with 20 emitters which can send trillions of cloud-forming ions into the atmosphere.
Over four summer months the emitters were switched on when the required atmospheric level of humidity reached 30 per cent or more.
While the country's weather experts predicted no clouds or rain in the Al Ain region, rain fell on FIFTY-TWO occasions.
The project was monitored by the Max Planck Institute for Meteorology, one of the world's major centres for atmospheric physics.
Professor Hartmut Grassl, a former institute director, said: There are many applications. One is getting water into a dry area.
'Maybe this is a most important point for mankind.'I wonder if this causes droughts downwind. BEGUN THIS WEATHER WAR HAS!
