Mumbai: The Air Quality Index (AQI) of Mumbai witnessed a slight drop during the morning hours on Friday, however, it shot up again by evening to 309, putting it in the ‘very poor’ category, which was again higher than Delhi (249) two days in a row.
The higher the AQI, the greater level of health concerns. The city also woke up to a colder morning on Friday with a minimum temperature of 18.6 degrees Celcius.
According to experts, the bad air quality is attributed to the weak winds blowing over the city because of which the pollutants remain in the atmospheric level and do not rise above it.
There is an anticyclonic circulation which has resulted in weak winds. Experts say it’s a rare phenomenon and the weather system is likely to experience a change in the coming week.
