| Abstract: | Accorqling to meteorological data from 1956 to 2011 observed by Nanning National Basic Weather Station, the distribution characteris- tics and the inter-annual variability characteristics of haze weather in Nanning were analyzed, the detrimental effect of haze weather on human health and traffic safety was elaborated. The results showed that the average annual value of haze weather days in Nanning is 20 d ,the inter-annual variation indicates the change of the preceding 45 years are relatively stable,the 11 years subsequent are more obvious. The monthly variation of haze weather is very obvious,the seasonal distribution characteristics of haze phenomena had the following trend： winter 〉 autumn 〉 spring 〉 summer. The distribution characteristics of monthly variation showed that maxima in December, and minima in July. Moderate or severe haze phe- nomenon poses serious threat to human health, traffic safety and the growth of crops. Haze led to the deterioration of air quality, can trigger respira- tory diseases and infectious diseases. Haze makes visibility deterioration, puts serious＂ impact on the land, sea and air traffic, resulting in frequent accidents. The haze takes serious impact on respiration and photosynthesis of the plant. Haze makes serious influence on regional climate, causes extreme climate events frequently. |
