The main purposes of this paper is to examine the pollutant transport capacity of wind-driven circulation in the Bohai Sea. Both the previously developed water-quality model and the seasonal mean wind-driven circulation model of the Bohai Sea are applied to calculate the temporal and spatial dispersal of the organic pollutant (COD) inflowing into the sea from 28 source sites along the coasts. The effect of seasonal wind on the COD concentration field produced by the tidal current dispersion has been investigated....

The main purposes of this paper is to examine the pollutant transport capacity of wind-driven circulation in the Bohai Sea. Both the previously developed water-quality model and the seasonal mean wind-driven circulation model of the Bohai Sea are applied to calculate the temporal and spatial dispersal of the organic pollutant (COD) inflowing into the sea from 28 source sites along the coasts. The effect of seasonal wind on the COD concentration field produced by the tidal current dispersion has been investigated. The obtained results show that the mean wind-driven current has a minor effect on the concentration field induced by the tidal current. Through numerical calculation of the net pollution transport by wind-driven current we find that the mean wind-driven circulation in Liaodong Bay is of advantage to the pollutant transport outflowing, and that in Bohai Bay, the winter mean wind-driven circulation has greater capacity for physical-purification then the summer mean wind-driven circulation. This is one of the main causes for the better water quality in the Bohai Sea in winter than in summer.

本文试验用渤海风海流模型和水质模型,考查了季风对潮扩散浓度场的影响以及平均风海流的污染输运能力。结果表明,潮流在污染扩散中起支配作用,而平均风海流对浓度分布的影响居次要地位。通过纯风海流的污染输运模拟发现,辽东湾的风海流终年有利于该区的污染扩散;而在渤海湾,冬季平均风海流具有比夏季更强的物理自净能力,这种季节性差异,可能是导致渤海冬季水质优于夏季水质的一个重要原因。

Dry deposition is the important process of scavenging of gross particle pollutants and sand dust. In this paper, a scheme of parameterization for dry deposition of particle which is fit for the pollution transport model is reached with a “two-layer” surface layer model. It includes the detailed meteorological conditions, the characteristics of surface and the physical and chemical properties of aerosol particles. According to the comparison between the numerical results and observed data, the scheme is reasonable in general, it can describe the main physical processes and mechanics about the dry deposition of the gross particle pollutants.
