Key Highlights
- AQI Update: Delhi’s Air Quality Index (AQI) recorded at 334, categorized as ‘very poor,’ with potential for further decline.
- Meteorological Factors: Low wind speeds (<5 kmph), low temperatures, and high humidity are contributing to pollution buildup.
- Improvement Trend: Compared to previous years, this December has seen fewer ‘very poor’ air quality days.
Current Air Quality Scenario
On Monday, Delhi’s AQI deteriorated further, following a gradual decline observed over the weekend. The AQI transitioned from ‘poor’ (294) to ‘very poor’ (307) on Sunday evening, peaking at 334 early Monday.
Reasons Behind Worsening Conditions
- Stagnant Weather: Lack of wind hinders pollutant dispersion.
- Temperature Drop: Cooler-than-average temperatures increase pollutant accumulation.
- Humidity Levels: High humidity intensifies pollutant concentration in the air.
Despite these setbacks, data shows that this December’s air quality is significantly better than recent years, apart from 2020, when COVID-19 lockdowns limited pollution.
North India Cold Wave and Dense Fog
Regions including Delhi-NCR, Punjab, and Haryana are experiencing cold wave conditions, with some areas recording temperatures as low as 1.7°C.
- Fog Alert: Dense fog expected on December 16 and 17, causing reduced visibility across North India.
Outlook and Concerns
- Officials predict no immediate relief as low wind speeds and stable weather conditions persist.
- However, the city’s air quality management efforts have shown improvement compared to earlier years, offering some optimism for the future.
Authorities and residents must stay vigilant and take protective measures to counter the ongoing pollution and weather challenges.
