Weather bureaus to cooperate on haze

THE Shanghai Meteorological Bureau will cooperate with its counterparts in Jiangsu and Zhejiang provinces to study and forecast weather phenomena that reduce visibility, such as fog and haze.

Haze is created by liquid or solid particles suspended in the air. The Yangtze River Delta Region has become one of the most seriously haze-polluted areas of the country. Climate experts warned yesterday that satellite images showed particulate pollution in the city was worse than some of the most seriously polluted areas of the United States.

Ozone, a colorless toxic gas, was another problem. The center found that from 2006 to last year, the city had increasing days when the ozone concentration was high. Jinshan District has the worst ozone problem. The district had 31 days when the ozone density was above standard levels, experts said.

Pudong New Area had 10 straight hours when the ozone concentration was higher than the standard on May 20 last year, which was a record length of time for high ozone concentration.

"High ozone levels will harm people's lungs, and will affect the growth of agricultural products," said Geng Fuhai, deputy director of the center.

The bureau will strengthen its monitoring of particulate matter and ozone in the air along with local environmental protection authorities during the 2010 World Expo, and issue alerts if needed.
