Delhi likely to get relief from smog today: MeT
9 Nov 2013 5:12 AM IST
‘Clouds will clear up from tomorrow (Friday) afternoon with the moving of the western disturbance eastwards,’ officials of the department said, but forecast foggy conditions from 9 November.
The forecast comes as a blanket of smog and foggy conditions continued to cover the city for the last three days, reducing visibility.
The thick smog was because of a reduction in the mixing height for the dispersion of pollutants due to lowering of the temperature, the Central Pollution Control Board had on Wednesday said.
The thick blanket of smog has not reduced in the last 24 hours 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 North-west India,’ said Rajendra Jenamani, in-charge 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.’
While the western disturbance brought rains giving respite from the smog, cloud cover was witnessed for most of the day.
However, with clear skies forecast from Friday onwards, there would be a fall of minimum temperature by 2-4 degrees over many parts of north-west India and some parts of adjoining central and west India on 9 and 10 November, the MeT department said.
During the last 24 hours, the city has experienced a maximum temperature of 27.5 degrees Celsius while the minimum settled at 14 degrees Celsius.. The maximum is expected to oscillate between 24-25 degrees between 9 to 11 November.
