Beijingers Warned of Heavy Sandstorm Season
2003/03/01
At least 10 sandstorms could hit Beijing this spring,
dumping tons of sand and grit both in central and suburban
areas, according to local meteorologists. Driven by high winds,
the annual storms sweep across the city before continuing east
to the Korean peninsular. As part of a source-control program,
the State Administration of Forestry and other government
authorities are doing all they can to reduce the onslaught by
creating a vast "green" arc of trees to the north of the
capital, and greening huge areas of land which, over the years,
have become virtual dustbowls due to erosion.
The meteorologists explained that, last year, north-western
China recorded above average spring rainfall and the Inner
Mongolia Autonomous Region even experienced several snowstorms.
But ground-surface humidity was not the sole deciding factor
behind sandstorms. Based on information collected by two
satellites monitoring the phenomenon, they believe many other
factors, such as the strength of cold air, ground-surface
vegetation and atmospheric circumfluence are all related to the
formation of the storms.
