Cities need to put efforts to deal w
ith pollution and clear the air.
Chinese cities will need to put efforts to clear up the sky when
a new department to improve regional air quality is set up by 2015, according to the latest plan released by the State Council．
Besides the existing pollution control program for S02, regional emission caps （区域排放上限） for other certain chemicals will be established in the three key air polluting areas— rhe Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region．Coal-consumption caps will also be tried out in some areas, according to the plan．
The plan is aimed at dealing with regional air pollution—such as acid rain and smog—which have become increasingly obvious in China in recent years and caused a severe threat to people's health, Zhang Lijun, vice-minister of environmental protection, said in an interview on Monday.
The air quality in a city affects the regions nearby because pollutants （污染物）can travel through the atmosphere, said Chai Fahe, vice-direc
tor of Chinese Research Academy of Environmental Sciences．
“So efforts to reduce air pollution in a single city, targeting a certain pollutant w
ill not oe enough," Chai said．
Zhang said the country's major industrial districts—the Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region—have recorded more than 100 misty days annually in recent years．
These three regions, home to at least 200 millio
n people, occupy only 6．3 percent of the country's area but consume 40 percent of the country's coal and produce half of its steel, according to official figures．
Studies also show that the visibility （能见度） in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s, as a result of air pollution．
Liaoning province, the Shandong Peninsula, Wuhan in Hubei province and its surrounding area, the Changsha-Zhuzhou-Xiangtan region in Hunan province, the Chengdu-Chongqing region, and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs, according to the plan．
The new plan also requires an improved air quality system, which will measure the pollution levels．"The current system, which only measures some major pollutants, cannot reflect the true picture．" said Chai．

ellites are helping to forecast（预报）the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere（大气）, because this is where the weather forms（形成）. They send these pictures to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
to the United Nations that a layer of ozone（臭氧层）in the atmosphere, which protects humans from harmful levels of ultraviolet（紫外线）radiation, will be thinner over the United States this summer．The thinner layer allows more ultraviolet rays from the sun to reach Earth．The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.
