2015年威海市酸雨变化特征及其影响因子的关系

为了解山东省威海市酸雨污染状况,进而为酸雨的控制提供参考依据,选取2015年威海市酸雨观测资料、气象因素数据,统计分析了威海市降水pH的季节变化和月变化,探讨了酸雨的变化特征,并对酸雨的成因做了初步分析.结果表明,2015年威海市酸雨强度和频率有明显的季节变化和月变化,降水pH随冬、秋、春、夏逐渐升高,而酸雨出现频率则按冬、秋、春、夏逐渐降低;相比于威海市周边地区,威海市酸雨污染相对较低,但值得引起注意;酸雨的出现与威海市当地气候、污染源和自然条件等因素有密切关系.

Variable Characteristics of Acid Rain and Its Influence Factors in Weihai City in 2015

In order to figure out the condition of acid rain in Weihai city, and provide some useful advice for the acid rain control, based on the observation data of acid rain and the related meteorological data in 2015 in Weihai, the seasonal and monthly variations of precipitation pH were analyzed, the characteristics of acid rain were primarily analyzed and its forming reasons were discussed. The results showed that there was obviously change in intensity and frequency of acid rain in Weihai in 2015. The rainfall pH valves was highest in summer, followed in spring, autumn and winter, while the acid rain frequen-cy was the highest in winter, followed in autumn, spring and summer. Compared with the surrounding area of Weihai, the acid rain pollution was relatively low, but it was worth to pay attention to the acid rain pollution. Acid rain weather was re-lated to the local climate, pollution sources and natural source and so on.
