Delhiites have been breathing much cleaner air than the week gone by that saw record pollution levels and worst smog in 17 years. However, we are afraid that it was a temporary relief as the deadly Delhi smog is all set to return. With this, pollution levels will also increase substantially.
According to Skymet Weather, moderate winds with the speed of 15 kmph to 25 kmph had cleared the thick layer of smog engulfing the national capital. Winds started picking up pace on November 7 and continued with the similar intensity on November 8 and 9 as well.
However, wind speed has decreased once again on Thursday, which is now between 10 kmph to 15 kmph. This is due to the approaching Western Disturbance that is likely to affect Jammu and Kashmir by the evening of November 11. It will also induce a cyclonic circulation over Central Pakistan and adjoining Punjab and Haryana.
At present, several parts of Delhi and the NCR are witnessing high PM 2.5 levels. While Noida is at a whopping 433, Delhi University is at 413, Pusa 385, Dhirpur 355, Pitampura 398, Delhi Airport 346, and Mathura Road 388.
As a result, wind direction will once again change from northwesterly to southeasterly or southwesterly. Wind speed will decrease further and moisture will also increase. All these factors coupled together will once again trap the available pollutants in the air and pollution levels will increase on Saturday.
However, to much respite, we do not expect the situation to be as grim as during the last few days as crop burning in the neighbouring states of Haryana and Punjab has almost stopped.
Low visibility, hazy sunshine and smog could be seen over Delhi-NCR during the weekend. Thereafter normal pattern of dry winds from northwest will resume from November 14, leading to clear sky conditions, reduced pollution levels and good visibility.
