Delhi AQI ‘Poor’ Despite End of Cold Wave — Will Rain Bring Relief?

Delhi's air quality has deteriorated once again, recording a 'poor' Air Quality Index (AQI) of 221 on Sunday, February 15, despite the end of the cold wave and the arrival of warmer, sunnier days. According to the Sameer app, 24 out of 40 monitoring stations in the national capital reported 'poor' AQI levels, while others registered 'moderate' readings, reigniting concerns among residents over breathing toxic air after a brief period of respite earlier this week.

The improvement in air quality at the start of the week was short-lived, as Delhiites find themselves grappling with polluted air even as winter chills fade. The city has transitioned to warmer conditions with sunny mornings, yet stagnant weather patterns appear to have trapped pollutants, pushing AQI levels back into the 'poor' category across multiple stations.

Weather analysts predict potential relief from upcoming disturbances. A Western Disturbance on February 13 primarily affected hilly regions, but another is expected on the night of February 16, potentially bringing scattered rain to parts of Haryana, Delhi, Rajasthan, Madhya Pradesh, and Uttar Pradesh. This is due to an induced cyclonic circulation over western Rajasthan and a trough extending from Delhi to Gujarat, accompanied by moisture inflow from the Arabian Sea, as noted in a Times of India report.

"Light, passing showers are possible, but widespread or prolonged rain is unlikely," said Mahesh Palawat of Skymet, speaking to the Times of India. Back-to-back weather systems are forecasted to influence the region around Tuesday and Wednesday next week, offering a slim chance of dispersion for the accumulated pollutants hovering over Delhi.

The India Meteorological Department (IMD) has forecasted comfortable daytime temperatures for Sunday, February 15, with a maximum hovering around 27 degrees Celsius and a minimum of about 11 degrees Celsius. These milder conditions mark a clear departure from the recent cold wave, though they have not yet translated into cleaner air for the city's residents.

As Delhi navigates this return to poor air quality, attention turns to whether the anticipated light showers will provide any meaningful relief or if persistent moderate-to-poor levels will continue to challenge public health in the coming days.
