Effects of Meteorological Factors on PM10 Pollution in Yantai Urban Areas

Article Preview

Abstract:

This paper makes analysis and statistics about the frequency distribution of average temperature, pressure, humidity and wind conditions between moderate pollution days of PM10(API>200) and conventional days from 2008 to 2010 in Yantai. The result shows that the frequency of PM10 pollution which occurred in winter is close to the sum of the other seasons. PM10 pollution days appears easily under such conditions: the average temperature below 10°C, average air pressure is higher than 101.0kPa, relative humidity is less than 70%, or average weed speed of 3-7m/s with the north-south wind.
