Delhi Pollution has been improving since the last two to three days. In fact, the pollution levels which were in very poor to sever category have now improved significantly and come under moderate to poor category.
On January 15, the overall AQI of the capital city has been recorded at 204, which comes under poor category. However, AQI up to 200 comes under moderate category. If we consider PM10, it settled at 156 which lies in moderate category and PM2.5 T 92 which is in the poor category.
The main reason for this improvement has been attributed to the moderate dry winds blowing over the region from northwest direction.
Now, by tomorrow, pollution in Delhi-NCR is likely to deteriorate marginally, as the speed of winds will decrease. However, further by January 17 and 18, pollution will increase even more and come under poor to very poor category.
This sudden significant change in increase of pollution over Delhi-NCR will occur, due to the approaching Western Disturbance over the hills which will change wind direction and their speed.
Moreover, due to the icy cold winds, both day and night temperatures have dropped over Delhi, Yesterday, the maximum temperature of Delhi was 4˚C below normal and minimum by 2˚C. However, now we expect maximums to rise marginally and minimums to remain near normal.
