The purpose of this paper is to shed light on the effects of sea and land breeze. One of the noticeable effects of sea and land breeze is the sulfate accumulation in the coastal areas. Sulfate accumulates as a result of sea and land breeze circulation systems.
Introduction.
According to Lyons (1995), with the lower pressure above the land and a high pressure above the water, conditions are ideal for a small sea breeze to develop. Wind blows from the ocean or sea towards the land along the pressure gradient in order to equalize the pressure. This phenomenon is called sea breeze. Land cools down more rapidly in the night than does the water of the sea. This results in air forming a high pressure, becoming denser, causing winds to blow towards the sea. This phenomenon is called land breeze. There are many effects of sea and land breeze on the environment such as pollution dispersion or accumulation and fog distribution (Lyons, 1995). Above all, the most dangerous effect of sea and land breeze is the accumulation of sulfate in the coastal areas as a result of sea breeze and land breeze circulation systems.
Observations.
Cass (1984) asserted that Sulfate aerosols contribute to the visibility problem of the region and affect acidity of rainwater and fog. As most of the pollutants of sulfur oxides emissions to city atmosphere occur in the form sulfur dioxide gases, there is significant interest in the means by which sulfur dioxide emissions ultimately lead to high particulate sulfate accumulation in the coastal areas.
Results.
On July 22, 1977, an atmospheric tracer study by means of sulfur hexafluoride was conducted in order to investigate the cause of the high particulate sulfate accumulations and concentrations seen in coastal Los Angeles County. The study found that circulation system of land breeze and sea breeze in the Los Angeles County increases the preservation time for sulfate creation in the aquatic environment and causes single air parcels to formulate multiple passes over huge coastal emissions sources.
