Weather officials said the drastic improvement in the National Capital’s air quality was due to rains because of back-to-back western disturbances and high-speed winds of up to 15-20 kmph sweeping through the region. SAFAR said the AQI may further improve to the “good” category due to prevailing rains and high-speed winds.
