According to the Air Standards Association, the wind direction is northwestward. However, due to the low speed, the pollutants do not help to spread. On December 15, 16 the wind speed increases and contributes to the spread of pollutants. This is likely to give the people of Delhi some relief from the polluted air. In the last 24 hours, the PM 10 level in the air was recorded at 284 and the PM 2.5 level at 168 micrograms per cubic meter.
According to the Indian Institute of Tropical Meteorology (IITM), on Wednesday, the wind speed was 5 to 10 km per hour and the mixing height was 1200 meters and the ventilation index was 3700 square meters. IITM expects all of these components to grow over the next two days. In this episode, over the next 24 hours, wind speeds are estimated to be in the range of five to 12 kilometers per hour, with an altitude of 1300 meters and a ventilation indicator of six thousand square meters per second. At the same time, on Friday, the wind speed will be eight to 15 km per hour, the mixing height will be 1750 meters and the ventilation index will be 1340 square meters per second.
According to the Central Pollution Control Board (CPCB), Delhi has an AQI of 363 in the last 24 hours. It was 367 the day before. In NCR, Ghaziabad Air is the only one in the poor segment with AQI 290. Other than that, the air in all the cities was very badly recorded. It is noteworthy that the air quality has been in a very poor category for the last three days. Environmentalists say pollutants are accumulating due to slowing wind speeds.
