Why Does Delhi's Air Quality Deteriorate in Winters?

One of the reasons behind a drastic dip in Delhi's air quality is슬롯 머신 사이트 추천the dip in temperatures. When temperatures go down in winter, the inversion height - which is the layer beyond which pollutants cannot disperse into the upper layer of the atmosphere - is lowered. The concentration of pollutants in the air increases when this happens. Besides, high-speed winds disperse슬롯 머신 사이트 추천pollutants in the air. However, during the winter season, Delhi sees슬롯 머신 사이트 추천a dip in wind speed.

Stubble burning is another factor that contributes to the rising of air pollution in Delhi. To get rid of paddy stubble as they plan to슬롯 머신 사이트 추천clear fields and sow wheat for the next cycle, farmers in neighbouring states of Punjab and Haryana resort to farm fires. Farmers set paddy straw and stalks on fire as it is the easiest way to get rid of it and that too at a low cost.슬롯 머신 사이트 추천The stubble burning season is around 45 days long.슬롯 머신 사이트 추천Delhi Air Pollution: Stubble Burning in Punjab, Haryana and Other Neighbouring Regions to Be Lesser This Year, Says CPCB.

Air Quality Dips in Delhi:

According to슬롯 머신 사이트 추천the System of Air Quality and Weather Forecasting And Research (SAFAR),슬롯 머신 사이트 추천the share of stubble burning in Delhi's pollution reached 46 percent last year. Dust pollution and슬롯 머신 사이트 추천vehicular pollution are the two biggest causes of dipping air quality in Delhi in winters. According to a study conducted by IIT-Kanpur, dust pollution contributes to 56% of PM 10 and the PM2.5 load at 59 t/d, the top contributors being road 38% of PM 2.5 concentration.

Vehicular pollution caused슬롯 머신 사이트 추천20% of PM 2.5 in winters in Delhi, said슬롯 머신 사이트 추천the IIT Kanpur study. Even though several initiatives have been launched to control rising air pollution in Delhi, air quality is likely to remain poor in the national capital as vehicles are back on the road after coronavirus-induced lockdown, the temperature is dipping and stubble burning has started.
