Meteorological Study on Prediction of Air Pollution (The 1st Report)

Today, it is very important to predict the occurrence of the air pollution, becauce if the air becomes dirty, clean air does not return easily by only stopping the issuing. Authors tried to analyze the phenomena of the air pollution in the city along the Suo Nada in Japan from the view of meteorology by using the data in July, Oct. and Dec., 1970. The result shows that the type of air pollution in this city is not by inversion layer but wind, because the occurence of SO_2 high concentration is related to the wind direction remarkably. Also, we calculated the concentration of SO_2 by Pasquill's Eq., and obtained pretty good result with measured data. Though tried to know the influence of wind velocity, we could not obtain notable result from the data used. We are going to continue the analysis moreover.
