Abstract:
Based on the regional air pollution data during heating seasons from 2004 to 2006 in the BeijingTianjinHebei region, associated with the sealevel pressure fields and high circumfluence characteristics, the synoptic weather patterns for air pollution are divided into five types: high pressure, cold front, low pressure, North China drytrough, and uniform pressure field. The high pressure type accounts for 40.0%. The regional air pollution process usually corresponds to an upperlevel circulation adjustment process. Continuous regional air pollution processes are usually affected by various kinds of synoptic patterns. Under the conditions of the surface convergence, lowlevel inversion and vertical sinking motion, pollutants are impeded to diffuse. The stable atmospheric stratification and influence of special terrain are the important reasons for the regional air pollution.
