Description
Summary:According to the data of black carbon aerosol in Wuhan central districts from July, 2015 to June, 2016, using the Meteoinfolab software, trajectory analysis, correlation analysis, multiple model fitting and other methods, this paper studies the associative relation between the black carbon aerosol in the central districts of Wuhan and the meteorological elements and monthly and seasonally, simulates the backward trajectory of the BC pollution events. The results are show as followed: Different wind directions and wind speed cast different impact on the mass concentration of BC. In the meteorological elements, the VSB casts greater influence on the mass concentration of BC. The back trajectory shows that, in summer the air masses in Wuhan regions mainly come from the waters near the North Pacific; in autumn, they are from the surrounding waters near the north and east of Canada; in winter, they are originated in the Arctic regions near Russia and Canada; however, in spring, the air masses stem from decentralized sources, and influenced by the high pressure from Mongolia, the pollutants fly through the traditional pollution regions such as Shanxi Province to Wuhan, resulting in a higher mass concentration of BC in January of all year. tables etc.
