Can rain really be stopped? It sounds like sci-fi, but it’s real. The technology is called cloud seeding – altering clouds to control weather.
In Vietnam and many countries, it has been used during national ceremonies, parades, and major sporting events.
How Cloud Seeding Works ⚙️
- Aircraft or rockets release chemicals (silver iodide, salt, dry ice).
- These particles trigger faster condensation inside clouds → making rain fall earlier or in a different area.
- Result: clouds “empty out” before reaching the target event location.
Why Called “Chasing Clouds”? ☁️➡️
It doesn’t literally chase clouds away – it shifts the timing and location of rainfall.
Real-World Applications 🌍
- Events: keep parades, festivals, and games dry.
- Agriculture: induce rain in drought-stricken regions.
- Military: historically used to disrupt enemy movement.
The Controversy ⚖️
- Expensive: millions of dollars per operation.
- Not 100% reliable.
- Environmental impact: possible chemical residue and disruption of natural cycles.
Final Take
Cloud seeding shows humanity’s ambition to hack nature. But it also raises questions: are we solving short-term problems while creating long-term risks?
👉 Bottom line: a mix of scientific marvel and double-edged sword.
