China to build a rain-making network three times the size of Spain

Tibetan Plateau region

This is industrial scale geo-engineering. From one researcher: “Sometimes snow would start falling almost immediately after we ignited the chamber. It was like standing on the stage of a magic show,” he said.

China is testing cutting-edge defence technology to develop a powerful yet relatively low-cost weather modification system to bring substantially more rain to the Tibetan plateau, Asia’s biggest freshwater reserve, says the South China Morning Post.

The system, which involves an enormous network of fuel-burning chambers installed high up on the Tibetan mountains, could increase rainfall in the region by up to 10 billion cubic metres a year – about 7 per cent of China’s total water consumption – according to researchers involved in the project.

Tens of thousands of chambers will be built at selected locations across the Tibetan plateau to produce rainfall over a total area of about 1.6 million square kilometres (620,000 square miles), or three times the size of Spain.

The chambers burn solid fuel to produce silver iodide, a cloud-seeding agent with a crystalline structure much like ice.

The chambers stand on steep mountain ridges facing the moist monsoon from south Asia. As wind hits the mountain, it produces an upward draft and sweeps the particles into the clouds to induce rain and snow.
