Abstract:With the synoptic charts and meteorological data, the relationships between heavy air pollution processes and weather systems, as well as meteorological factors, are analyzed by statistical methods for 41 typical heavy air pollution processes from 2003 to 2007 in Fuzhou. On the basis of statistical analysis, the main circulation patterns that bring heavy air pollution are identified for winter, spring and summerautumn seasons, respectively, and a quasiquantitative analysis is made of the relation between surface meteorological elements and heavy pollution processes. The meteorological indexes and synoptic conceptive models for heavy air pollution weather processes in Fuzhou are established.
