Key Takeaways

  • Iran deployed aircraft to spray cloud-seeding chemicals over the largely dried Lake Urmia basin.
  • Authorities dispersed silver iodide and salt particles into clouds to try to induce rainfall.
  • Nationwide rainfall is about 89% below average, marking Iran's worst drought in decades.

Cloud-seeding at Lake Urmia

Iran has resumed cloud-seeding flights over the heavily shrunken Lake Urmia basin in the northwest as an emergency response to a historic drought.

Officials and state media say aircraft, and in some reports drones, will disperse seeding agents to try to induce rain and boost runoff into catchment basins near the lake.

The operation is presented as a technical effort to stimulate precipitation amid dramatic surface water loss at Urmia.

Lake Urmia has largely dried into a salt plain after prolonged aridity.

Nationwide drought and shortages

The campaign comes amid an extreme nationwide rainfall shortfall.

Multiple outlets report autumn precipitation was roughly 89% below long-term averages, calling it the driest autumn in about 50 years.

Tehran recorded its lowest rainfall in roughly a century.

Reservoirs and major dams are at historic lows and near empty.

Authorities warn some cities could face imminent water shortages.

The situation has prompted emergency conservation measures and sharp cuts to water use.

Cloud-seeding operations

They say aircraft will disperse particles such as silver iodide or salt into clouds, and some reports also mention ground generators.

Iranian authorities say they have domestic cloud-seeding technology and plan ongoing operations.

Media note the seeding aims to increase runoff into catchment basins to marginally raise water availability rather than restore the lake in the short term.

Iran drought warnings and impacts

Iranian leaders have warned of severe societal impacts if rains do not arrive.

President Masoud Pezeshkian and other officials have publicly raised the prospect of water rationing, emergency measures and even evacuation scenarios for Tehran.

Authorities are already imposing strict water-use cuts in affected areas.

Media reports link these warnings to the prospect that, without precipitation, major population centers could face acute shortages of drinking water and services.

Others note regional cloud-seeding activity and prior Iranian accusations that countries such as Israel and the UAE attempted to divert or block rain.

Regional media reported that claim, but international outlets presented it as an allegation rather than a verified fact.
