INFLUENCE OF WIND SPEED AND DIRECTION ON THE CITY AIR POLLUTION LEVEL BY FUEL COMBUSTION PRODUCTS
In the article there are results of investigation into the influence of wind speed and direction on the average air pollution level of carbon oxide and nitrogen dioxide in the administrative centre of the region. Critical wind speed and directions when there is formation of the maximum air pollution in warm and cold seasons are detected. According to the data of the cartographic analysis the role of motor transport emission in the air pollution of individual city districts is revealed. The highest average air pollution level caused by nitrogen dioxide in the warm season in the area of the first and the second stationary sites was registered if the wind direction was south and north-west but in the cold season – if the wind direction was south-west and west. The most unfavorable wind speed was less than one meter per second.
