In the 1940s, scientists discovered that dropping particles of silver iodide into cloud tops, made the tiny water droplets condense and could stimulate precipitation.

在 1940 年代，科学家现将碘化银颗粒滴入云顶，使微小的水滴凝结并可以促进降水。

The UAE already uses a technique called cloud seeding to try and increase their rainfall, which means they intentionally release certain compounds, like silver iodide, into the clouds.
