An official of the meteorological department said that the northwest winds are blowing during the day and bringing pollutants produced by burning stubble. At night, pollutants accumulate due to freezing of air and decreasing temperature. According to the ‘Air Quality Monitoring and Weather Forecasting and Research System’ (Safar) of the Ministry of Earth Sciences, there were 882 incidents of stubble burning on Saturday in Haryana, Punjab and areas near the border.

It said that stubble burning in the PM2.5 pollutants was about 19 percent on Saturday. The Air Quality Early Warning System of the Ministry of Earth Sciences has said that the air circulation index is expected to be 12,500 sqm per second which is favorable for scattering of pollutants. When the air circulation index is less than six thousand and the average air speed is less than ten km per hour, there is an unfavorable condition for scattering of pollutants.

The system said that the effect of burning stubble on the air quality of the national capital can be “greatly increased by Monday”. Officials said on Saturday that in Punjab and Haryana this season so far this year compared to last year. The incidence of stubble burning is high due to the premature harvesting of paddy and the unavailability of laborers working in the fields due to corona virus epidemic.

The Central Pollution Control Board (CPCB) on Friday said that the seasonal conditions for widespread spread of pollutants have been ‘highly unfavorable’ since September this year in Delhi as compared to last year. Board member secretary Prashant Gargava had hoped that the occurrence of stubble burning would be lower this year than in 2019 due to non-basmati paddy cultivation in less area. It is noteworthy that non-basmati paddy straw is considered useless as fodder because it contains high amount of “silica” and hence the farmers burn it.
