- 摘要:
- 针对不同气象条件和天气过程对污染物扩散条件的影响,利用2011-2017年4月四川盆地6个城市每天8个时次的地面观测资料,运用国标法、罗氏法和联合频率法计算了大气混合层的高度,并分析了混合层高度的变化特征; 同时结合国家环保部数据中心2014-2017年4月的AQI日平均资料,对混合层高度与AQI做了相关性分析。研究结果如下:混合层高度的3种计算方法中联合频率法具有更好的精确性和代表性,更能反映实际情况; 四川盆地的混合层年平均高度为587.2 m,变化范围在530～660 m,并呈抬高趋势; 月平均高度为591.26 m,变化范围在440～770 m,最低值出现在秋、冬两季,最高值出现在春、夏两季,说明春、夏两季大气的扩散条件比秋、冬两季要好; 近年来冬季的混合层高度大致上也呈现抬高的趋势,表明冬季的扩散条件有所转好; 一天之中混合层高度在午后14时达到最高,夜间02时最低。混合层高度与AQI总体来说表现为负相关,其中达州混合层高度与AQI的相关性最好,相关系数为-0.22,但其相关性根据季节的变化而存在波动,一般在冬季混合层高度与AQI为显著的负相关,而在春、夏两季则出现正相关。
- Abstract:
- In view of the impact of different meteorological conditions and weather processes on the diffusion conditions of pollutants, the ground observation data of 8 times per day in 6 cities in the Sichuan Basin from April 2011 to April 2017 were used to calculate the atmosphere by using the national standard method, the Roche method and the joint frequency method. The height of the mixed layer was analyzed and the characteristics of the height of the mixed layer were analyzed by combining with the AQI daily average data from the data center of the Ministry of Environmental Protection from April 2014 to April 2017. The correlation between the height of the mixed layer and the AQI was analyzed. The results are as follows: The joint frequency method has better accuracy and represent ativeness in the three calculation methods of mixed layer height, and it can reflect the actual situation more effectively; The annual average height of the mixed layer in the Sichuan Basin is 587.2 m, and the change range is between 530 and 660 m. There is a trend of elevation; The monthly average height is 591.26 m, and the change range is between 440 and 770 m. The lowest value occurs in autumn and winter, and the highest value occurs in spring and summer. This shows that the diffusion conditions of the atmosphere in spring and summer are better than those in autumn and winter. In recent years, the height of the mixed layer in winter has also shown a tendency of elevation. This indicates that the diffusion conditions in winter have improved. In one day, the height of the mixing layer reaches the highest at 14:00 and the lowest at 02:00. The mixed layer height is negatively correlated with the overall AQI. The correlation between the height of the mixed layer in Dazhou and the AQI is the best, and the correlation coefficient is -0.22, but the correlation fluctuates according to the seasons, generally in the mixed layer height in winter. There was a significant negative correlation with AQI and a positive correlation in the spring and summer.
