Warning system for sandstorms to be launched

China will launch a nationwide monitoring and early warning system for sandstorms this month, which is expected to cut the country's economic losses by at least 245 million yuan (30 million U.S. dollars) per year, experts say.

The estimation is based on the present frequency of the destructive storms, which occur 18 to 20 times a year, hitting mainly north China, particularly its northwestern region.

Sources in this capital of northwest Gansu Province said the monitoring and early warning system will perform data collection, transmission, processing and database management and study the cause and development of sandstorms, sound alarms and evaluate their potential harm.

Functions of the system

Upon completion, the system will be helpful to governments at all levels in their decision-making process, and will provide integrated meteorological services to ordinary citizens and other users, said Xie Jinnan, director of the Gansu Provincial Meteorological Bureau.

The system, which includes four sub-systems for monitoring, communication, alarm services and technical assurance, will be built in Gansu, Xinjiang, Inner Mongolia, Ningxia, Shaanxi and Beijing, which are either the origins of China's sandstorms or passageways for them.

As a leading team of the system construction, the Ganxu bureau has started to upgrade its meteorological station, install additional radars, build broadband transmission facilities and set up all necessary devices to monitor land moisture and water tables. It will soon open a website with updates of the causes and development of sandstorms and ways to protect against them.

Nature Continues to Kick up a Storm: Analysis

In recent years, it seems that sand storms are affecting Chinese people's lives more frequently and extensively. As this spring draws near, more sand storms are expected. Among the many Chinese scholars probing the reasons and controlling measures of the sand storms, Wang Shejiao, of the Northwest Historical Environment and Economic Social Development Research Centre under the Shaanxi Normal University, has put forward a rather unique view. >>details
