What impact did the 'double-dip' La Nina have on air quality in different regions of India in 2022-23
Rare 'triple-dip' La Nina improved air quality in north India, increased pollution in peninsular region in 2022-23, study says
1. The 'double-dip' La Nina in 2022-23 had varying impacts on air quality across different regions of India.
- North India experienced improved air quality due to a rare 'triple-dip' La Nina event, which helped in reducing pollution levels.
- Conversely, the peninsular region faced increased pollution levels as a result of the La Nina phenomenon.
- The unusual weather patterns associated with La Nina influenced the monsoon circulation and wind patterns, impacting the dispersion of pollutants in the atmosphere.
- These changes in air quality were attributed to the complex interactions between La Nina, regional weather systems, and local pollution sources.
