摘要
大气污染与气象因素密切相关。大气污染物中的颗粒物(PM10、PM2.5等)浓度与风速、风向、气压、温度、湿度、降水量、大气稳定度等气象因素的关系复杂。该文主要探讨大气污染物中颗粒物浓度与气象因素之间的关系以及介绍了国内外研究者所建立的在不同气象条件下大气污染物浓度的预测模型,为控制大气污染提供科学依据。
Many researches have shown that atmosphere pollution and meteorological factors are related closely. The relations between the particle concentration in atmosphere and meteorological factors including wind speed,wind direction,air pressure,temperature,humidity,precipitation and atmosphere stability vary in different researches. Taking into consideration the complexity of meteorological factors and the components and concentration index of particles,it is more reasonable to do multi-factor analysis. But the results of multi-factor analysis also show obvious diversity and complexity due to different research objects,methods and measuring indexes. Therefore,different models for the prediction of particle concentration are needed for the factors such as area,time and meteorological conditions always change.
