Delhi Dust Storm: Learn what caused the dust storm in Delhi-NCR

According to weather experts, northwest India will experience extreme heat for five days, and the dry soil is a result of the lack of rain. Strong winds began blowing here about midnight, causing dust to begin flying. The head of IMD's regional weather forecasting centre, Kuldeep Srivastava, reported that morning winds were blowing at a pace of 30-35 km/h.

He said that the wind speed would decrease over the day, causing the dust to settle in the ground. The dust concentration has multiplied, according to V.K. Soni, director of IMD's Environment Monitoring and Research Centre. At 4 am, PM10 levels were 140 micrograms per cubic metre; at 8 am, they were 775 micrograms per cubic metre.
