Toxic Air Quality in Delhi: Delhi’s air quality remains highly variable, ranging from “severe” to “very poor” conditions, compelling authorities to implement the most stringent limitations as outlined in Stage 4 of the Graded Response Action Plan (GRAP). In the coming days, however, Delhi residents may experience some solace in the face of alarming air pollution levels caused by a recent western disturbance.
Light to moderate precipitation or snowfall is anticipated from the Western Disturbance over the Western Himalayan Region through November 10 and over the adjacent plains on November 9, according to the India Meteorological Department.
It caused a wind direction shift toward the southeast and an increase in wind speed of approximately 5 kilometers per hour from tranquil conditions (0 speed) at approximately 6:00 a.m. on Tuesday, according to Hindustan Times.
The National Capital Region has experienced a negligible reduction in air pollution levels due to a marginal increase in wind speed.
“The western disturbance has brought relief, as predicted by us.” “This will persist for several days,” stated M. Mohapatra, director general of the IMD.

NORTH INDIA MAY EXPECT RAIN THIS WEEK.
It is likely that it will rain in Himachal Pradesh from November 8–10, Uttarakhand from November 9–10, Punjab, Haryana, Chandigarh, and West Rajasthan on November 9. This is because of the Western Disturbance and an induced cyclonic circulation at a lower tropospheric level over Northwest Rajasthan and the surrounding area.
The upcoming Diwali celebration in the Delhi-National Capital Region (NCR) on November 12th may provide some relief from the current air pollution levels, as precipitation is expected in certain regions of northern India.
According to Skymet Weather’s vice president of climate and meteorology, Mahesh Palawat, the situation in Delhi could potentially improve by November 11th, when the western disturbance subsides and northwesterly winds increase in velocity to 15–20 km/h. He said, “That will aid in the dispersion of pollutants.”
The Supreme Court severely criticized state administrations in the NCR when it decided that stubble burning had to stop in order to stop the air pollution from getting worse. The highest court acknowledged that the burning of vegetation continues to be a significant source of pollution in the NCR.
CURBS IN DELHI DUE TO THE APPEARANCE OF GRAP-IV
Stage 4 of the Graded Response Action Plan (GRAP) imposed measures in the Delhi-National Capital Region (NCR) on Sunday in response to the severe air quality index (AQI). These measures include prohibitions on diesel vehicles, construction, and remote work for offices.
A directive from the CAQM said that the sudden rise in AQI was mostly due to bad weather, a lot of agricultural fires, and slow-moving winds from the northwest that brought pollution to Delhi.
As per the Commission for Air Quality Management in NCR and Adjoining Areas (CAQM), an eight-point action plan in accordance with GRAP Stage IV is implemented throughout the entire NCR as of today.
