Air improves, Delhi to get warmer: IMD
NEW DELHI: A change in wind direction improved Delhi’s air on Sunday, pulling the air quality index (AQI) from the ‘severe’ to the ‘very poor’ category. Meanwhile, forecasters at the India Meteorological Department (IMD) also said the coming week is likely to see warmer days, with pollution expected to fall further.
On Sunday, the minimum temperature at the Safdarjung weather station, which is considered the official marker for the city, was 5.7 degree Celsius, while the maximum temperature was 15.3°C, five degrees below the season’s normal.
According to IMD scientists, the wind direction changed from north-westerly to easterly.
Kuldeep Srivastava, head of IMD’S regional weather forecasting centre, said, “Winds will remain easterly throughout the week. Minimum temperatures in Delhi fell last week since we received winds from Jammu & Kashmir and Himachal Pradesh, but the coming week will be comparatively warmer.”
He added, “The easterly winds have also picked up speed, which means that pollutants have also dispersed significantly.”
Central Pollution Control Board recordings show that on Sunday Delhi’s overall AQI was 347, in the ‘very poor’ zone. On Saturday, the average AQI in was 407, in the ‘severe’ category.
The System of Air Quality and Weather Forecasting and Research (Safar) has also forecast cleaner air days for Delhi.
