A light dust storm descended on Lanzhou city, provincial capital
of northwestern China's Gansu Province, on Tuesday evening.
Meteorologists say the storm was mainly caused by relatively high
temperatures, dry air and low rainfall.
Meanwhile, Lanzhou Morning Post reports severe sandstorms
and strong winds hit two counties in Gansu called Minqin and
Liangzhou on Tuesday afternoon. The sandstorm in Minqin lasted four
hours, reducing visibility to only 600 meters.
The report says Minqin County suffers severe sandstorms on 29
days every year. It has become one of the major sources of dust and
sand in northern China.
