Delhi got enveloped under a thick layer of dust for the third consecutive day today. This has worsened the air quality of the national capital and its adjoining cities, thereby forcing Delhiites to come out of their houses wearing masks again.
The severity of the dust over Delhi can be traced out form the fact that the air quality has worsened and has reached to hazardous levels with the PM10 being recorded at more than 700 μg/m3.
The reason for this layer of dust can be attributed with the winds blowing from Rajasthan and from the neighboring Pakistan that are hotter with soaring mercury levels. The weather over these regions has remained continuously dry. Due to the absence of rains, the dust and sand over these regions are loose in nature.
Moreover, the winds blowing over the region are strong in nature, and thus, these are transporting the loose dust from the sand areas over most parts of Northwest India, including over Delhi.
According to Skymet Weather, this layer of dust is the reason that Delhi’s temperatures have been witnessing a rising trend.
