- Delhi Chief Minister has said cloud seeding is essential for the national capital as it could play a key role in controlling rising pollution levels during the winter season.
- Temperature Inversion: During winter, the air near the ground becomes cooler than the air above it.
- This inversion layer traps pollutants (such as particulate matter and gases) close to the surface, preventing their vertical dispersion into the upper atmosphere.
- Low Wind Speeds: Winds are generally weaker in winter, which reduces horizontal dispersion of pollutants, allowing them to accumulate in the lower atmosphere.
- Prevailing wind patterns carry this pollution towards Delhi, worsening air quality. Read More
