摘    要:对地面风场的研究表明,厦门存在局地和海陆风环流,自1955年以来年平均风速、混合层厚度均呈现下降趋势,大气污染物的水平和垂直扩散能力也呈下降趋势。降水酸度随海拔高度的变化情况表明,海陆风环流有利于酸性污染物的积累,且锋面降水过程中的光化学污染加重了降水的酸化程度。

关 键 词:酸雨  海陆风环流  混合层厚度  厦门

Abstract:Research on surface wind field indicated the presence of local circulation and sea and land breeze circulation in Xiamen. Since 1955 the annual average wind speed and the mixed layer thickness showed the downtrend,which indicated that the horizontal and vertical diffusion capacity of atmospheric pollutants were also declined. The acidity of precipitation changed with the altitude indicated that the sea and land breeze circulation was beneficial to the accumulation of acidic pollutants, the photochemical pollution in the frontal precipitation process increased the degree of acidification of precipitation.
Keywords:Acid rain  Sea and land breeze circulation  Mixed layer thickness  Xiamen
