=> This storm originated over Afghanistan, Pakistan, and border areas of Rajasthan, on February 3, 2022.
=> In the month of January, a storm originated in the Middle East and brought haze and dust to north-western Maharashtra, Rajasthan and Gujarat.
=> Low day temperatures, high relative humidity, weak, low-speed winds, and coldness of air are the contributing factors to bad air above the city.
=> Minimum temperature has fallen from 19.4 degrees Celsius on February 7 to 17.8 degrees on February 8.
=> In Mumbai, bad air is cleaned out regularly by a strong sea breeze. But Low wind speeds results meant that local pollutants in city have not been effectively dispersed.
