Direct Evidence of Reduction of Cloud Water after Spreading Diatomite Particles in Stratus Clouds in Beijing, China

Figure 1

Schematic picture for the effect of changes in cloud nuclei (CCN) on precipitation. The red regime represents for the enhancement of precipitation with increase of CCN, and the blue regime represents for the reduction of precipitation with increase of CCN. The green dot indicates the threshold for the enhancement/reduction transition point.
