Then I will tell you the analysis(??n?l?s?s) of the causes [k?:z] of haze [he?z] weather:
Haze is a muddy phenomenon that countless particles of aerosol that suspend in the air, such as smoke and dust. It is the result of some favorable weather condition and increasing discharged pollutants from human.
First of all, the anomaly atmospheric[??tm?s?fer?k] circulation is conducive [k?n'dju:s?v] to the formation of haze. It is more easily to appear in autumn and winter which increase the air humidity. [hju:?m?d?ti] Secondly, the high concentration of aerosol makes great effort on the visibility [?v?z??b?l?ti], which is the main reason of haze weather. The aerosol is some solid or liquid particles suspended in the air which is called PM 2.5 in Chinese.
They are mainly from Motor vehicle[?vi??k(?)l], the burning of coal, second nitrate['na?tre?t], second sulfate [?s?l?fe?t], combustion of Biomass ['ba???m?s], industry, Road dust and so on. In northern china, the carbon from the burning of coal makes the concentration of aerosol increase significantly.(make加动词原
