Relationship between the land/sea breeze circulations and the air pollution dispersion over the coastal area of Kuwait.

摘要

The purpose of this study is to examine the variability of winds during the summertime over the coastal area of Kuwait, to identify the effect the sea-land breeze circulations have on the winds, and determine the effects of the wind patterns of pollution concentration in the region. Nearly all of the severe air quality conditions over the coastal areas are correlated with the sea-land breeze recirculation. The Persian Gulf plays an important role in the advection of pollutants from the sea to the coastal areas. The daytime sea breeze and the nighttime land breeze limit the ventilation of air masses and recirculate contaminants, and implies that air pollutants will be partially recirculated over the shoreline, accumulating in levels of pollution higher than would otherwise be expected. This paper indicates that sea breezes frequently cause a strong influence on local air pollution events in shoreline area.
