Pollution in Delhi-NCR has been hovering around poor category for the past many days. The reason for poor air quality can be attributed to the persistent fog cover over the national capital.

The local pollutants and smoke particles normally mingle with the condensed water vapor near the earth’s surface and remain suspended for a longer duration. In fact, vehicular traffic emissions, dust from construction sites and other various pollutants are also in abundance over Delhi and adjoining regions.
In wake of this, pollution levels kept shuffling between poor and very poor category over the city. As per Skymet Weather, the pollution levels decrease over Delhi-NCR whenever the winds are strong or there is rain.

These strong winds carry away the pollutants and spread them in wider areas, leading to significant improvement in the air quality. Similarly, rain washes away the pollutants from the atmosphere.
Same was the case today when Delhi-NCR recorded rains of varying intensity. Therefore, we now expect the pollutants in the atmosphere to settle down, leading to much cleaner air.
It is expected that the pollution will not increase at least for the next three to four days over the city. After that, winds would become light again. Rain is also not predicted in the near future. Hence, the pollution levels will crawl back to poor and thus, we can say that the relief would be short-lived.
