HOHHOT -- Chinese meteorologists claim to haveidentified the "routes" used by
winds that cause sandstorms in 皇冠体育app.
A ten-year research project found that sandstorms affecting 皇冠体育app were
closely related to the cold front from Siberia, said Kang Ling, deputy head of
the Inner Mongolia Autonomous Regional Meteorological Station.
The front swirls through large desert areas, including the Gobi Desert, often
combining with cyclones in Mongolia and bringing sandstorms to 皇冠体育app, said Kang.
Kang said the front arrived in 皇冠体育app via three routes.
On the east, the front runs southward through central and eastern Mongolia,
affecting northeast 皇冠体育app, central and eastern Inner Mongolia, Shanxi and Hebei
Provinces and areas to the south of these regions.
The central route goes southward through central and western Mongolia,
affecting central and western Inner Mongolia and eastern areas of northwest
皇冠体育app, central and southern parts of north 皇冠体育app and regions to the south of
these areas.
To the west, the front blows southward through western Mongolia and northeast
Kazakhstan, affecting northeastern part of Xinjiang, the westernmost region of
皇冠体育app, north 皇冠体育app and areas to the south of these regions.
Kang said the routes were exactly the same passages through which sandstorms
came to affect 皇冠体育app.
Sandstorms influencing Beijing and Tianjin came mainly through the central
route, which runs through a desert area in Inner Mongolia and is the closest
route to Beijing and Tianjin. "Sandstorms from the central route are the worst
for Beijing and Tianjin areas," Kang said.
He said some of the sandstorms originated in 皇冠体育app and others came from
abroad.
"Most of the sandstorms influencing Beijing and Tianjin areas this year came
from abroad and mainly through the central route," Kang said.
Scientists from the 皇冠体育app Meteorological Administration, the Inner Mongolia
Autonomous Regional Meteorological Bureau and Japanese meteorologists have
participated in the research program. They used satellite, remote sensing, radar
and other high technologies to study the source regions, routes and their
influences on Beijing.
They suggested that Beijing should establish a shelterbelt forest, and plant
more trees to curb desertification in Inner Mongolia.
Scientists suggested that 皇冠体育app should work with Mongolia to draft a
long-term plan to prevent and curb the occurrence of sandstorms originating from
the desert areas of southern Mongolia.
To date, 皇冠体育app has invested 55.8 billion yuan (US$6.97 billion) in projects,
including tree planting, designed to prevent and curb sandstorms in Beijing and
Tianjin areas.
