A dust storm is a strong wind that carries clouds of fine dust, soil, and sand over a large stretch, which mainly occurs in arid and semi - arid regions. In case of a dust storm, due to lot of heating, the water from the clouds evaporates before it could land. So soil is dry and the severe winds lift this soil up to 500 metres above the land.
Scientists say high temperatures played an important role in intensifying the storms that originated in the desert area of north - west India and further west. Climate scientists have also predicted that droughts will become more severe in this part of South Asia with climatic changes.
And because of that, dust storms like the most recent ones, could occur more frequently. India's Meteorological Department has warned that more storms can occur across a wider area before the weekend.
During the weekend and into early next week, temperatures over 38 C (100 F) will be found across much of India. This includes areas in eastern Rajasthan and western Uttar Pradesh.
These temperatures are near normal for early May, but anyone outdoors should be sure to stay hydrated by drinking plenty of water and to wear protective clothing. Extraneous activities should be avoided during the heat of the day in order to avoid heat - related illnesses.
