Delhi is currently struggling with a thick layer of smoke as the air quality index remains in the 'very poor' category for the fifth day. With the minimum temperature dipping 3 C below normal, pollution levels have worsened, making the air more toxic and unhealthy to breathe. According to experts, the combination of low temperature, calm winds and trapped pollutants will increase breathing issues, especially among children, elders, and people who have long-term and heart diseases. As Delhi enters its peak winter pollution phase, doctors are advising people to stay protected and avoid unnecessary outings.

Delhi AQI: Why The Air Remains Very Poor

Delhi AQI has remained consistently above 300, and the main reason behind that is slow wind speed and increasing humidity in the atmosphere. These conditions combine to prevent pollutants from dispersing, causing smoke to accumulate near the ground. Factors like vehicle emission, industrial smoke, dust from construction sites and seasonal biomass burning, continue to add to the city pollution burden.

  • AQI Sunday :377
  • AQI Monday 4Pm: 351
  • AQI Tuesday, 8 Am: 344

Delhi's Cold Weather, Making Pollution Worse

The minimum temperature stayed at 9.6 C day after this season, lowest of 8.7 C

Meteorologists say:

  • Minimum temperature will be between 9 C and 11 C till Thursday
  • Wind from east will reduce the temperature below 11 C after November 21

Cold wind and clear sky can became the reason of radiational cooling, which will trap pollutants at ground level and making smoke denser.

  • Sunday:12.8%
  • Monday: no official data shared with contribution is lesser
