Since past few days, both day and night temperatures over Delhi-NCR are above normal. And, as per the records, in last 48 hours, the minimums over Delhi are dropping gradually and will continue to do so in coming 48 hours as well.
On Monday morning, Safdarjung observatory recorded 8.6 degree-Celsius which is the lowest minimum of this season.
Since there is a gap in the passage of western disturbances, thus dry and cold winds from the north-west will blow over the national capital territory and it’s surrounding regions. Thus, bringing further drop in the minimums.
Chill during early morning and late evenings will be felt in coming days. The minimums might come below normal, whereas the maximums will reach near normal. As per the weathermen, till the time maximums don’t reach the mark of 16 degree-Celsius (+/-), chill during day time will not be felt. Sky will remain clear with sunshine in offing. No chances of fog are to be seen, had the fog persisted for longer duration, cool weather would have been felt during daytime as well.
As per the experts, pollution level will remain in ‘very poor’ to ‘poor’ category for the coming 24 hours. Thereafter, there can be a marginal improvement as the wind speed of north-westerlies is expected to increase. Though the improvement will not be significant as the wind speed will remain between 10-15 km/ph. Till the time the wind speed doesn’t gear up around 15-20 km/hr, the pollution levels will continue to persist in very poor to poor zone.
As per Skymet, we do not expect relief from bad air quality for another one week. The pollution levels will continue to oscillate from very poor to poor. No relief is foreseen because the Western Disturbance which is approaching around December 6 is expected to pace down the wind speed and the direction of winds would also change. No rain or major weather activity is also predicted which would have otherwise helped in fading away the pollution levels.
