ẢNH HƯỞNG CỦA THỜI TIẾT về ô nhiễm Giới thiệu Khi dân số thế giới và công nghiệp hóa phát triển, ô nhiễm không khí (hình 1) trở thành một vấn đề dần dần nghiêm trọng hơn. Việc kiểm soát ô nhiễm không khí đòi hỏi sự tham gia của các nhà khoa học từ nhiều ngành: vật lý, hóa học và kỹ thuật cơ khí, khí tượng học, kinh tế, và chính trị. Số lượng kiểm soát cần thiết phụ thuộc vào kết quả của các nghiên cứu y tế và sinh học.

The control of air pollution requires the involvement of scientists from many disciplines physics chemistry and mechanical engineering meteorology economics and politics. The amount of control necessary depends on the results of medical and biological studies. The state of the atmosphere affects first many types of pollution. For example on a cold day more fuel is used for space heating. Also solar radiation which is affected by cloudiness has an influence as smog production. Second atmospheric conditions determine the behavior of pollutants after they leave the source or sources until they reach receptors such as people animals or plants. The question to be answered is given the meteorological conditions and the characteristics of the source or sources what will be the concentration of the pollutants at any distance from the sources The inverse question also is important for some applications given a region of polluted air where does the pollution originate Finally the effect of the pollution on the receptor may depend on atmospheric conditions. For example on a humid day sulfur dioxide is more corrosive than on a dry day. Meteorological information is needed in three general areas of air pollution control 1 In planning control measures wind climatology is required. Pollution usually must be reduced to a point where the air quality is substantially better than the existing quality. In order to assure improved quality certain standards are set which prescribe maximum concentrations of certain pollutants. In order to reach such standards the points of origin of the pollution must first be located traditionally everybody blames everybody else for the unsatisfactory air quality. Given possible pollution sources tracing of air trajectories coupled with estimates of atmospheric .
