Analysis Of Haze Prone Weather And The Local Climate

With the continuous development of social economy, people’s living standards improve, people’s attention on climate and environment are more and more, but the problem of air pollution in China has become more and more serious. In recent years, frequent fog and haze, haze has been formed in four local area, China are: the Yellow Sea Huaihai area, Sichuan Basin, Pearl River Delta and Yangtze River delta. We found that, the haze of multiple weather areas, are often relatively "climate". To explore a series of scientific problems, the primary task is to study the relationship between haze weather and local climate, the second is to study the cause of the local climate, so as to achieve the reasonable development of air quality improvement, prevention and control of pollution to the haze. Based on this, this paper uses several methods of data mining field and remote sensing method, to study the haze weather and local climate correlation from the following four aspects:(1) the autocorrelation analysis model by using space, between space adjacent regions due to atmospheric transmission caused by the "local" haze, results show that the haze component exists in the aggregation state of the space, with another area source between adjacent regions is obvious. A "high spatial distribution"( High pollution index of pollution index in the area around the area is also very high) main research area, has obvious "local" haze weather.(2) the aerosol optical thickness and surface temperature, correlation comparison two inversion results and similarity, results show that, the surface temperature was positively related to the study area of the aerosol optical thickness and the region; "analysis of related factors of local haze weather".(3) the vegetation index inversion research area, and the surface temperature inversion and the linear correlation analysis, the results showed a significant negative correlation between the two, namely the formation of local climate has strong links with land use, and then from the point of view of social development, using the grey correlation analysis model, economic development and human activities the effects of haze pollution components, the results show that the social development and human activities in the haze weather and local climate are related, especially the population is more intensive and more developed industrial area, social development of emissions, city road construction has a great contribution to the haze pollution components.(4) influence from air dynamics perspective, using correlation analysis, grey correlation model to study the influence of meteorological conditions on haze weather. The results showed that weather conditions affect the haze diffusion component and aggregation, there is a certain correlation between them; also through the acquisition of two sites on the outskirts of the city and the correlation data analysis, further proof of the haze weather and local climate.
