“High wind speed has affected the temperature and brought it down slightly. These winds are mostly coming from the north-west direction and will continue on Tuesday as well. The average wind speed on Monday was 45 kmph,” said Kuldeep Srivastava, a scientist at IMD.

The average speed of winds on Monday was 45 kmph. Cloudy sky will prevail throughout the week, and gusty winds with a speed of 30-40 kmph is likely to prevail till Tuesday, IMD predicted.

While March mostly saw moderate days, the AQI deteriorated to 189 (moderate) on the last day of the month.

According to the Air Quality Early Warning System for Delhi (AQEWS), AQI is expected to stay in the moderate category for the next few days. “The air quality is likely to be in the moderate category from April 2 to April 4. The outlook for the subsequent six days is that the air quality is likely to be in moderate category,” the AQEWS bulletin said on Monday.

Air pollution experts said that the sudden spike in AQI on Sunday and the subsequent decline on Monday can be attributed to wind conditions. “In metropolitan cities like Delhi, certain factors like vehicular pollution constantly contribute to air pollution. However, depending on the speed of surface winds, the air quality can improve. Strong surface winds can lead to cleaner air and the vice versa,” said Avinash Chanchal from Greenpeace, India.
