Sunny days to grace rest of December in Delhi, but nights to get chilly

While the remaining days in December will remain more or less sunny, the nights are all set to get colder, according to the India Meteorological Department (IMD) officials. The minimum temperature will settle around 8 degrees Celsius over the next three to four days, and officials believe commuters will have respite from dense fog till December 21.

Even as the maximum temperature at 18 degrees Celsius on Sunday was one notch below the normal, weather analysts maintained that the day temperatures would not dip much till around Thursday, which is also expected to result in better air quality during this period.

“The minimum temperature is going to hover between 7 and 9 degrees Celsius over the coming week. Not much change is expected in the day time temperature. This means that the days will be relatively sunnier while the nights are set to remain cold,” said R Vishen, Scientist-Incharge, Regional Meteorological Centre (RMC), IMD.

Mist or shallow fog is expected to remain over Delhi-NCR during the early hours. The visibility will improve to around 500 m from the present poor condition of less than 200 m.

The weather conditions along with improved wind speed will help dispense the accumulated heavy pollutant particles in the air, resulting in better air quality.

“The wind speed will remain around 4 m per second over the coming week, dispelling the pollutants and giving some relief to residents from the bad air quality days. This is due to normal north-westerly winds returning to northern India,” Vishen said.

Environmentalists, however, opined that despite less fog, the air quality may not see considerable improvement because of increased humidity levels coupled with vehicular emissions in the Capital.

Meanwhile, the Central Pollution Control Board (CPCB) is yet to notify its ‘grade response plan’to deal with different levels of pollution, as directed by the Apex Court earlier this month.

Experts said other emergency measures adopted by the Delhi government and the Lieutenant Governor (LG) to deal with pollution in specific areas need to be implemented with immediate effect in order to sustain improved air quality.
