Moscow, Mar 30 (IANS/RIA Novosti): Authorities in Moscow have revealed they will spend almost $4 million to ensure city residents be able to enjoy two rain-free national holidays in the coming months.

A notice posted Thursday on Russia's state tender website called on companies to apply for the job to provide "meteorological protection for the city".

The technique of cloud dispersal, or cloud seeding, dates back to the Soviet era. The substances used can include silver iodide, dry ice and cement powder.

Whichever company gets the job can expect payment of around 121 million rubles ($3.9 million).

The holidays that the Moscow administration wants to provide good weather for are Victory Day, May 9, and Russia Day, June 12, which are celebrated with mass outdoor gathering and parades.

While Muscovites may benefit from the cloud seeding, residents in areas around the city have reported that practice often pushes any prospective poor weather over them.
