Mumbai is experiencing south-easterly winds for the past few days, which are not strong enough to blow away the pollutants in the air. Pollutants are getting accumulated in the air and remaining suspended in the lower atmosphere for longer periods leading to poor AQI,” said Mahesh Palawat, meteorologist and climate expert from Skymet Weather
In the morning, these particulate matters and water vapour suspended in the air are combining to form smog, which is affecting visibility. The low wind speed is the primary factor behind poor AQI. Being an island city, Mumbai’s AQI is determined by wind blowing from the sea,” Palawat added.
