| 摘 要： | 利用大连酸雨观测站2006～2009年观测资料和气象资料,对大连酸雨的变化特征以及酸雨的形成与气象条件的关系进行了分析。结果表明,大连是我国北方酸雨影响较强地区之一,发生频率达66%,降水pH值最低达3.49。秋季降水酸性最强,春季最弱;酸雨频率出现最多的季节是夏季,冬季最低。大连酸雨出现频率与风速和空气中可吸入颗粒物的浓度呈反比关系;雾天由于稳定层结和充沛的水汽有利于酸雨出现;连续性降水并不意味着空气中酸性物质的减少,在连续性降水的所有个例中,第2天酸性增加的占42%。

| Abstract: | Using the observation data and meteorological records of acid rainfall observation station in Dalian during 2006-2009,the change features of acid rainfall in Dalian and the relationship between the formation of acid rainfall and meteorological conditions were analyzed. The results showed that Dalian was one of regions with strong acid rainfall in Northern China,and the frequency of occurrence was up to 66% and minimum pH reached 3.49,indicating a strong acidity characteristic. The acidity was the strongest ... |
