The skies above Japan turned purple before the country’s worst storm in 60 years hit.
Before the heavy downpours and strong winds pounded Tokyo and the surrounding areas, residents captured pictures of the bright pink and purple sky.
The eerie phenomenon, which often precedes or follows a major storm, is the result of “scattering”.
This happens when molecules and small particles in the atmosphere influence the direction of light, causing the light to scatter.
Heavy storms wash away the larger particles which have absorbed more light and scattered wavelengths more evenly. This makes the colours of the sky appear more vivid.
