Industrial Pollution Linked to Localized Snowfall Through Cloud Freezing
Scientists have discovered that aerosols from factories can trigger ice formation in clouds, leading to increased snowfall near industrial sites.
- A new study reveals that industrial pollution particles act as ice-nucleating agents, converting supercooled liquid clouds into ice clouds.
- Researchers identified 67 industrial sites across North America, Europe, and Asia where pollution-induced snowfall was observed.
- Satellite and ground-based radar data showed reduced cloud cover and increased snowfall downwind of industrial hot spots.
- The ice clouds formed by pollution reflect less sunlight and absorb more infrared radiation, affecting local atmospheric conditions.
- Further research is needed to understand the broader climate implications of this phenomenon and the specific pollutants involved.
