“…They deduced that the summer part was more pronounced for daytime hours associated with photochemical production. Besides, Pirovanoa et al (2007) presented the ozone peaks and found that the shape of ground-level ozone plumes could be affected by variability in circulation through simulations and posited such differences in relation to meteorological fields in a complex terrain area. The vertical distribution of ozone and 13 VOCs in the boundary layer of Mexico City have further been investigated by Velasco et al (2008) recently to improve our understanding of the complex interactions between those trace gases and meteorological variables.…”

This paper reviews the interrelationship among boundary layer, urbanization, and evolution of ozone, with particular emphasis on how boundary layer dynamics and urbanization affects the evolution of ozone under different meteorological and climatological conditions. The aim of this work is not only to provide an exhaustive investigation of individual ozone episodes but to look at the underlying issues and hypotheses that are available for understanding the evolution of ozone. The review concludes with a summary of the current state of knowledge and outlines some of the remaining questions. It is the intention of this paper to serve as an ecumenical reference to the community for reappraising the relation of boundary layer climate to the evolution of ozone in an urban setting, especially on a peculiar feature of ozone dynamic, nocturnal ozone maxima. To date, there is still no overarching consensus on the mechanisms that lead to its formation. The importance of levels of urbanization and advantage of ascertaining the substantial weights of the respective mixing height and emission structure in exploring the relationship between ozone evolutions should not be overlooked.

“…Studies conducted in coastal areas have also demonstrated the role of sea breeze circulation in smog episodes (Lyons et al, 1995;Kambezidis et al,1995Kambezidis et al, , 1998Melas et al, 1995;Clappier et al, 2000;Evtyugina et al, 2006;Pirovano et al, 2007). Due to the large horizontal and vertical variations in meteorological parameters caused by the different diurnal heating cycles at the sea/land boundary, coastal meteorology still represents a challenge for air pollution modelling and assessment of ozone behaviour.…”

Numerical simulations compared with measurements are used to investigate the effect of sea breeze circulation on the ozone accumulation over a highly industrialized peninsula in southern Italy, where high levels of ozone concentration are often registered. A frequent meteorological phenomenon in this region during weak summer synoptic conditions is the development of complex sea breeze systems from the coastlines, with convergence areas within the peninsula. A case study characterized by strong winds alternating with sea breeze circulations was selected. The simulations show that during weak synoptic conditions, sea breezes transport ozone and its precursors over land from the sea, as well as from the coastlines where the largest industrialized districts are localized. The overlapping breezes lead to ozone accumulation in the area where sea breeze convergence occurs. This may explain the high values of ozone registered close to the sea breeze convergence lines. The comparison between predictions and experimental data indicates that the numerical system successfully reproduces both weather and ground level ozone concentration in different meteorological conditions, resulting in a fundamental tool for both scientific comprehension of the evolution of air contaminants and interpretation of the monitoring data.

“…Pollutant concentrations in Marseille are highest just upwind of the sea-breeze front (the front's propagation speed is lower than the wind speed, and the vertical mass flux at the front is less than the horizontal flux within the sea-breeze, allowing pollutants to accumulate just behind the front, with some upward transport; (Drobinski et al, 2007). The accurate simulation of the fine-scale features of sea-breeze mesoscale transport in the Marseille area is crucial in order to predict both ozone peaks and ozone plumes (Pirovano et al, 2007).…”

Mass tracking for chemical analysis: the causes of ozone formation in southern Ontario during BAQS-Met 2007

Abstract.A three-level nested regional air pollution model has been used to study the processes leading to high ozone concentrations in the southern Great Lakes region of North America. The highest resolution simulations show that complex interactions between the lake-breeze circulation and the synoptic flow lead to significant enhancements in the photochemical production and transport of ozone at the local scale. Mass tracking of individual model processes show that Lakes Erie and St. Clair frequently act as photochemical ozone production regions, with average mid-day production rates of up to 3 ppbv per hour. Enhanced ozone levels are evident over these two lakes in 23-day-average surface ozone fields. Analysis of other model fields and aircraft measurements suggests that vertical circulation enhances ozone levels at altitudes up to 1500 m over Lake St. Clair, whereas subsidence enhances ozone over Lake Erie in a shallow layer only 250 m deep. Mass tracking of model transport shows that lake-breeze surface convergence zones combined with the synoptic flow can then carry ozone and its precursors hundreds of kilometers from these source areas, in narrow, elongated features. Comparison with surface mesonet ozone observations confirm the presence, magnitude, and timing of these features, which can create local ozone enhancements on the order of 30 ppbv above the regional ozone levels. Sensitivity analyses of model-predicted ozone and HO x concentrations show that most of the region is VOC-limited, and that the secondary oxidation pathways of aromatic hydrocarbons have a key role in setting the region's ozone and HO x levels.
