摘要：On coastal environments, the pollution potential is mainly governed by the land sea breeze circulations. Asimulation experiment was carried out by taking the temperature difference (Tland-Tocean) and the resultingcirculation acceleration (dv/dt) was also estimated. The influence of sea breeze on local air quality was observed byselecting SO2 as a reference species at different points of Visakhapatnam. The relative meteorological parameterslike temperature, relative humidity, wind speed and direction and the resultant SO2 concentrations were observed. Atypical ‘sea breeze day’ was studied and the observations were presented in this study. At different points of thestudy area, the onset time of sea breeze front and the related meteorological parameters were also observed alongwith SO2 concentrations. The air pollutant concentrations of typical pollutant, SO2, at different sampling pointswere measured round the clock. Simultaneously measurements of wind vector, relative humidity, temperature andthe concentration of SO2 was also observed. In this article we study a characteristic of the sea breeze fronts withregards to the inland moments are attempted and their role in local air quality is also discussed.
