Delhi and the NCR region have been battling with a hazardous air quality index during the last week. However, rain gods came to the rescue of the people of Delhi.
A western disturbance-induced cyclonic circulation over North India has given widespread rain over Punjab, Haryana, Delhi, parts of Uttar Pradesh and Rajasthan. The pollutants which were suspended in the air for many days, have washed away.
The air quality index of Delhi and NCR is still in the moderate to poor category. We do not expect a spike in pollutants over the Northern Plains including Delhi for at least the next 3 to 4 days as the winds from the Northwest direction will continue with moderate intensity.
The two weather factors, moderate to strong wind and rain are essential to wipe out the pollution. Rain has already occurred. Now the winds over gain speed and will not allow the pollutants to settle down. Moderate winds will keep dispersing the pollutants.
The festival of Diwali is around the corner. We all know that the burning of crackers leads to some pollution. Fortunately, the recent rain and moderate winds will not allow the accumulation of pollutants.
