【摘要】 基于台州气象站2008~2013年酸雨资料进行统计分析,得出台州酸雨变化特征及趋势。降水p H值、导电率K值的概率分布呈正态分布和对数正态分布,多年平均降水p H值4.48,导电率K值35.7μS·cm-1,酸雨率80.9%,台州降水容易形成酸雨,雨水酸度较高,比较清洁。酸雨形势时空表现不同,W-NW-N方及SW方为酸雨偏重区域,冬春季降水酸性污染程度较夏秋季重。年均降水p H值4.32~4.64、导电率K值31.3~42.3μS·cm-1,酸雨率73.1%~86.8%,酸雨形势年际波动总体变化不大,但显示出微弱转好态势。降水量、雾天、近地面风场都对酸雨的变化有重要影响。更多还原

【Abstract】 Absract: Base on the Statistical analysis of acid rain data during 2008-2013 in Taizhou meteorological station,This pape reaches the characteristics and trend of acid rain in Taizhou.The probability distribution of Rainfall p H value and Conductivity K value are normal distribution and lognormal distribution, average annual rainfall p H value is 4.48, Conductivity K value is 35.7μS·cm-1, acid rain rate is 80.9%, Taizhou precipitation is easy to form acid rain, rainwater acidity is higher and cleaner. The acid rain situation is different in time and space, the heavier acid rain area is W-NW-N and SW, the acid pollution degree of winter and spring precipitation is more important than summer and Autumn. The annual average of precipitation p H value is 4.32~4.64, Conductivity K value is 31.3~42.3, acid rain rate is 73.1%~86.8%,acid rain situation changed little over all annual fluctuation,but it shows a better situation. Precipitation,fog,and near-surface wind fields have important influence on the change of acid rain.更多还原
