A New Method to Discern Haze Using Meteorological Parameters and Air Pollution Factors

This paper analyzes the nature and differences between haze and mist, discusses the disputes and the inefficient prevailing methods of distinguishing them (not able to grasp the essence of haze - Air Pollution phenomenon), on the basis of understanding the nature of the formation of haze, the paper discusses the difference between haze and mist and their relationship. The article then analyzes theoretically the relationship of atmospheric visibility, the relative humidity and the atmospheric concentrations of fine particles. From the theoretical point of view, it is possible to distinguish haze and mist by studying the relationship of relative humidity, visibility and the atmospheric concentrations of fine particles. The article further uses specific location - for example Xiamen City to study the corresponding relationship between meteorological parameters and air pollution factors, especially in hazy and misty weather conditions, the relationship of relative humidity, the visibility and PM10 concentration. Data analysis results support the conclusions of theoretical analysis, that is, in different weather conditions, the relative humidity, the atmospheric visibility and the concentration of PM10 fine particles have a significant correlation. To use such different relationship, the haze and the mist can be the differentiated. Based on the theory and the data analysis, the article proposes a new method of distinguishing haze: that is to use meteorological parameters and air pollution factors to distinguish haze and mist, the formula is also provided. It also discussed the figure choice of the formula for the relative humidity and the concentration of fine particles PM10. Finally, the article discusses the problems of this new approach and the future works need to be carried out.
