降雨被假设受到液滴电荷的影响，液滴电荷与流经云层的全球电路电流有关。这是通过检查人工放射性释放后主要全球电路电流的增加来检验的。远离污染的设得兰群岛的日降雨量分布发生了显著变化。在核武器试验期间，日降雨量变化了24%，当地云层光学增厚。这支持了额外电离引起液态水云电致微物理变化的预期。
Rainfall is hypothesised to be influenced by droplet charge, which is related to the global circuit current flowing through clouds. This is tested through examining a major global circuit current increase following release of artificial radioactivity. Significant changes occurred in daily rainfall distribution in the Shetland Islands, away from pollution. Daily rainfall changed by 24%, and local cloud optically thickened, within the nuclear weapons test period. This supports expectations of electrically induced microphysical changes in liquid water clouds from additional ionisation.
