New Delhi, Nov 6 (UNI) The Delhi Government has awarded a study to JNU's School of Environmental Sciences, to analyse characteristics of smog, reasons for its formation and management.

The Environment Department has sought the comprehensive study to cover all the four season's pollution levels, temperature, humidity, wind speed and direction.

The report will be submitted in a year's time.

The National Capital Territory of Delhi has been experiencing haze during the morning hours for the last four to five days.

The condition is not uncommon during the month of November, according to the Meteorological Office Director.

When low level inversion (temperature increase upto about 1 km height) and light winds generally lead to this type of conditions.

''Whenever such low level inversion (stable atmosphere) occurs, the pollutants especially the solid particulate matter (smoke and dust particles generated by vehicular traffic, industrial and construction activity remains suspended in the lower atmosphere,'' the Met Office said.

As the winds are also light, the particulate matter suspended in the atmosphere is neither mixed nor dispersed away.

''This results in hazy/smog conditions prevailing over the region.'' UNI NR NC RK2110
