摘要
利用昆明2015~2017年空气污染物资料和2015~2017年地面气象资料,对昆明夏季的臭氧浓度情况进行分析,发现在6月份昆明的臭氧浓度最高,7月其次,8月最少。同时对一天中的臭氧浓度变化情况进行分析,发现一天中臭氧浓度最大值出现在北京时下午3点左右,臭氧浓度最小值出现在北京时上午8点左右。在对臭氧浓度和气象条件进行相关性分析之后发现,相对湿度与臭氧浓度相关性最大,且呈负相关。对臭氧浓度与气象因子做逐步回归分析,得出昆明夏季臭氧浓度在有雨日和无雨日的预报方程。
Based on the air pollutant data of 2015-2017 and the ground meteorological data of 2015-2017 in Kunming, the ozone concentration in summer in Kunming was analyzed. It was found that the ozone concentration in June was the highest, in July the second, and in August the lowest. At the same time, the change of ozone concentration in a day was analyzed. It was found that the maximum value of ozone concentration in a day appeared around 3:00 p.m. Beijing time, and the minimum value of ozone concentration appeared around 8:00 a.m. Beijing time. After the correlation analysis of ozone concentration and meteorological conditions, it is found that the correlation between relative humidity and ozone concentration is the largest and negative correlation. A stepwise regression analysis of ozone concentration and meteorological factors was performed to obtain the prediction equations of Kunming summer ozone concentration in rainy and non-rainy days.
