摘要: The characteristics of meteorological conditions related to changes in atmospheric environment on Jeju Island were investigated during recent years (2010-2012). This analysis was performed using the hourly observed data variables (air temperature, wind speed and direction) air pollutants (O3, PM10, SO2, NO2, CO). Out 5 pollutants, O3 PM10 concentrations have frequently exceeded national environmental standards study area period, with relatively higher than others. 2010 2011 somewhat those 2012, their highest mostly spring followed by fall. Nighttime (with high concentration levels) almost similar its daytime concentrations, due less titration very low NO target part increase resulting from transport processes. effect variations also clarified correlation between these variables, e.g. exceedance frequency criteria strong westerly/northwesterly winds (e.g., polluted regions China). overall results this suggest that likely be caused (horizontal vertical) rather contribution local emission sources.
