New Delhi: Light showers and winds yesterday failed to provide relief to Delhiites from the cover of smog which has enveloped the city for the past few days.
The thick blanket of Smog has not reduced in the last 24 hour and spread in higher areas of northwestern India. It is despite the fact that winds were blowing over Delhi and other stations during this period at a speed of 15 kmph, a MeT official said.
“This stagnation of smog layer was observed irrespective of light rains in parts of Delhi early this morning and other some parts of Northwest India,” said Rajendra Jenamani, Incharge of MeT department at the IGI airport.
“Now it depends, how much it rains tonight due to the ongoing Western Disturbances (WD).” There was significant improvement in the post Diwali smog and visibility improved to 2,500 metres from 500 metres on Tuesday evening.
“The concentration of particulate matter (PM10) in air had reduced by 50 per cent for Anand Vihar and other stations of Delhi to 700 microgram per cubic metre from 1,500 microgram per cubic meter prevailing on Tuesday evening,” he said, adding but today, there was hardly any improvement either in the PM levels or visibility levels.
Jenamani said the latest analysis of winds pattern and cloud coverage through satellite and Doppler Weather Radar (DWR) shows that “smog coverage has not reduced further during last 24 hours over Delhi.”
It has now spread more in Delhi, Jaipur, Ludhiana, Chandigarh and other cities of northwestern India in last 24 hours, where the visibility had remained below 1,000 metres this evening.
