Dependence of the Surface Ozone Concentration in the Harima District on the Insolation and the Wind

[摘要] Surface ozone concentrations measured for nine months in the Harima district were analysed to find a relationship with some meteorological factors. Emphasis is put on the high concentrations of ozone in the afternoon in late spring to summer.In general, the daily maximum ozone concentration is proportional to the integrated insolation. The day-to-day fluctuation in the daily ozone maxima is mostly caused by the various patterns of the winds. Dependence of the particularly high ozone values on the location of the sites can be explained by the effect of advection due to land and sea breezes.
