【摘要】 为探讨新乡市气象因素对大气颗粒物浓度的影响,本研究于2017年3月1日-2018年2月28日对新乡市大气颗粒物PM2.5和PM10进行采样,并监测同期的气温、气压、相对湿度等气象因子。发现新乡市PM2.5和PM10的年均值分别为68.09μg/m3和68.09μg/m3;颗粒物浓度季节变化特征为冬季浓度最高,夏季浓度最低,秋季浓度高于春季浓度。新乡市全年的主导风向为东北风和西南风。气温、气压、相对湿度、平均风速与PM2.5和PM10的质量浓度有较强的相关性,气温和风速是影响PM2.5和PM10浓度的主要因素。更多还原

【Abstract】 In order to understand the influence of meteorological factors on atmospheric particulate matter concentration of Xinxiang city,atmospheric particulate matter including PM2.5,PM10 and also meteorological data from 1, 3, 2017 to 28, 2, 2018 were collected. The annual average concentration of PM2.5 and PM10 were68.09μg·m-3 and 68.09μg·m-3 respectively. The seasonal variation was the highest concentration in winter,the lowest concentration in summer and the higher concentration in autumn than in spring of particulate matter concentration. The northeast wind and southwest wind were the prevailing wind direction in the main urban area of Xinxiang city. The temperature,atmospheric pressure,relative humidity and average wind speed had a strong correlation with the mass concentration of PM2.5 and PM10. The temperature and wind speed were the main factors affecting the concentration of PM2.5 and PM10.更多还原
