"Massive Fog Shrouds China
Most of northern China is shrouded in one of the most massive fogbanks ever recorded. The fog consists of water droplets mixed with dozens of different kinds of pollutant, and is so thick in places that visibility is down to a hundred yards.
According to China's Meteorlogical Bureau most of China is involved in this extraordinary phenomenon. The heavy fog is looming over northern China, southwestern China, northeast China's Liaoning Province and the lower reaches of the Yangtze River.
In some areas, visibility is minimal and air quality is dropping to dangerously low levels.
The fog, which covers 217,000 square kilometers, has been caused by a concentration of still, humid air over the region. It is expected to be blown out to sea over the weekend, when a cold front clears the air.
The gigantic pollution cloud will then move out into the Pacific where it will either dissipate or continue across the ocean, depending on weather conditions.
Dust clouds from China routinely reach the US Pacific Northwest, and, in recent years, pollution from the region has been detected in the stratosphere worldwide."
