Due to occurrence of dust storm, Delhi air quality deteriorated on Wednesday, System of Air Quality, Research and Weather Forecast (SAFAR), a unit of Ministry of Earth Sciences (MoES) has recorded high concentration of Particulate Matter (PM) 10.
The SAFAR marked "Orange" to Capital air on Air quality Index (AQI). The PM 10 was recorded at 272 micro cubic per gram and in its air forecast the SAFAR updated the number with 355 (µgm-3)n and gave status - Very Poor.
PM 2.5 was also recorded relatively poor, the concentration was fluctuated between 64 - 84 µgm-3.
While Met and climate experts said that the reason of frequent thunderstorm is surface heat which leads to heat waves and resulting in occurrence of dust storm.
Recently , Delhi witnessed three major high -intensity dust storm (May 2 , May 13 and May 15)
While MeT has predicted and forecast more thunderstorm and dust - storm activities, air quality will further deteriorate with high ratio iof dust particles in air.
According to weather experts, there are chances that there could be more instances of gusty -dusty dust and thunderstorm with high momentum of winds.
The rising surface temperature is triggering heat wave and dust storm. Incidentally, on January 18 this year , NASA has released a research based on the MeT data of centuries and mentioned that the global surface temperature of the Earth in 2017 was the second-warmest in recorded history since 1880.
