Rare ‘industrial snowfall’ thought to be caused by pollution recorded in UK

Phenomenon whereby moisture condenses around particles of pollution was noticed near Heathrow in January

A rare phenomenon known as “industrial snowfall” appears to have occurred near Heathrow airport earlier this year, according to a study.

Satellite imagery shows three large, white bands on the ground in parts of Surrey despite relatively dry conditions in the area at the time. The snow, which was recorded on 23 January, was distributed near industrial facilities south-east of Heathrow airport.
