China’s innovative use of drone technology to enhance rainfall in Xinjiang showcases the power and controversy of weather modification.
In July 2023, China conducted a groundbreaking weather modification experiment in Xinjiang, using drones to seed clouds and increase rainfall by over 4% across 3,089 square miles in a single day. Led by Li Bin, a senior engineer at the China Meteorological Administration (CMA), this project highlights both the potential and the challenges of cloud seeding in addressing water scarcity in arid regions. This article explores the science behind the operation, its environmental implications, and a taste of Xinjiang’s culture with a traditional *Laghman* recipe.
The Science of Cloud Seeding in Xinjiang
On July 9, 2023, two models of medium-sized drones ascended to 18,000 feet over the Bayanbulak Grasslands, releasing 1 kg of silver iodide—a common cloud-seeding compound—across four flights. The operation generated over 70,000 cubic meters (18.5 million gallons) of additional precipitation, equivalent to filling 30 Olympic-sized swimming pools, as reported by the South China Morning Post. The results were published in a peer-reviewed paper in the Chinese-language journal Desert and Oasis Meteorology on April 10, 2025.

The project, supported by 24 automated ground stations, satellites, and drone fleets since 2021, demonstrated high precision and scalability. Statistical analysis of 50 years of climate data confirmed a 3.8% rainfall increase, closely matching simulations predicting a 4.3% boost.

Environmental and Geopolitical Implications
Xinjiang, home to the Gobi and Taklamakan deserts, faces severe water scarcity due to desertification and glacial retreat in the Tianshan Mountains, which lose 0.8–1.15 square miles of ice annually. While cloud seeding offers a potential solution, concerns arise about its environmental impact. Silver iodide, though used in small quantities, may accumulate in ecosystems, posing risks to aquatic life and biodiversity, according to the World Meteorological Organization.

In the 2000s, Chinese provinces accused each other of stealing clouds, highlighting potential transboundary conflicts.

While no evidence supports claims of Bill Gates funding this project, his involvement in solar geoengineering research has sparked online speculation.

Xinjiang’s history of water management dates back to the Silk Road era, when the region developed the *karez* system—underground channels that transport water from mountains to oases. These engineering marvels, some over 2,000 years old, sustained agriculture in the arid region and remain in use today. The modern cloud-seeding program echoes this ingenuity, adapting ancient resourcefulness to 21st-century challenges.
Taste of Xinjiang: Traditional Laghman Recipe
Xinjiang’s cuisine reflects its diverse cultural heritage. *Laghman*, a dish of hand-pulled noodles with a spicy meat and vegetable sauce, is a beloved staple. Here’s a simple recipe to bring Xinjiang’s flavors to your kitchen:
Ingredients (Serves 4):
- 400g all-purpose flour (for noodles)
- 1 tsp salt
- 200ml water
- 300g lamb or beef, thinly sliced
- 2 bell peppers, sliced
- 1 onion, sliced
- 2 tomatoes, diced
- 2 cloves garlic, minced
- 1 tbsp soy sauce
- 1 tsp cumin powder
- 1 tsp chili powder
- 3 tbsp vegetable oil
- Salt and pepper to taste
Instructions:
- Make the Noodles: Mix flour, salt, and water to form a dough. Knead for 10 minutes until smooth. Cover and rest for 30 minutes. Divide into 4 pieces, roll into thin ropes, and stretch into noodles. Boil in salted water for 3–5 minutes until al dente. Drain and set aside.
- Prepare the Sauce: Heat oil in a wok. Stir-fry lamb or beef until browned. Add garlic, onion, and bell peppers; cook for 3 minutes. Add tomatoes, soy sauce, cumin, chili powder, salt, and pepper. Cook until vegetables soften, about 5 minutes.
- Combine: Toss cooked noodles with the sauce. Serve hot, garnished with fresh cilantro if desired.
Conclusion: Balancing Innovation and Responsibility
China’s drone-based cloud seeding in Xinjiang demonstrates the potential of technology to combat water scarcity, but it also raises environmental and ethical questions. As weather modification expands globally, transparency and international cooperation are crucial to mitigate risks. What are your thoughts on weather modification?
