A sandstorm resembling a huge wall of sand travelled for more than 60 miles (100km) in China’s northwestern province of Qinghai.
The storm appeared last Wednesday before it advanced to the east of the region with the help of westerly wind, according to state broadcasters
A lack of precipitation, excessive snow melt and strong evaporation resulted in dry soil and exiguous spring vegetation.
A super-strong Mongolian cyclone developed on the bare and loose ground, and easily blew and transported large amounts of sand particles into North China.
Furthermore, top-ranking anomalies (sea ice shift in the Barents and Kara Sea, and sea surface temperatures in the east Pacific and northwest Atlantic) were found to induce the aforementioned tremendous climate anomalies in the dust source area.Â
