(Institute of Atmospheric Physics, Chinese Academy of Sciences) The researchers used standardized factors to objectively identify haze events in China's national capital region of Beijing-Tianjin-Hebei from 1980 through 2013. They identified 49 persistent haze events, each lasting for at least three days with limited visibility. The scientists also found that the haze events had one of two specific circulation patterns, both of which can produce a strong sinking motion in the atmosphere.
