After a brief period of relief, the air quality in the national capital slipped into the ‘severe’ category yet again on Tuesday with the overall AQI settling at 425. However, the situation might get better November 15 onwards owing to an increase in wind speed and a rise in temperature.
In conversation with India Today, weather expert Dr Naresh said that Delhi will witness an increase in wind speed due to a western disturbance in Afghanistan. “Winds gusting up to 5-8 km per hour right now will be blowing at around 20 km per hour after November 15,” Dr Naresh said.
Dr Naresh also said there will be a rise in temperature of up to three to four degree Celsius after November 15. Notably, an increase in wind speed and rise in temperature will both help in bringing down pollution levels in the Capital because when the temperature drops, the air gets cold and heavy which doesn’t let the pollutants over the ground to disperse.
Delhi has been reeling under alarming pollution levels for the last couple of weeks due to stubble burning in the neighbouring states of Punjab and Haryana, a dip in temperature, a decrease in wind speed and local pollutants. After which, several steps were taken by the Kejriwal government, including the reintroduction of the odd-even scheme from November 4 to combat the menace of air pollution.
However, after only three days of suspension of the car rationing scheme, air quality in the national capital which had improved to the ‘poor’ category went back to the ‘severe’ category on Tuesday morning.
