The Meteorological Setting of a Particulate Air Pollution Episode During November 2009, in Western Macedonia Industrial Area, Greece
A particulate air pollution episode of relatively long duration was recorded in the industrial basin of Western Macedonia, Greece, during November of 2009. A case study of the meteorological aspects of this episode is presented in this paper, based on the combined utilization of PM10 concentration measurements, surface and lower atmosphere parameters and simulations. An Omega blocking pattern which gradually transformed to a high-over-low pattern prevailed over central and southern Europe during the episode’s period. The absence of significant convection in the middle and lower troposphere combined with a weak horizontal wind field near the surface and the reduced mixing height, resulted in the pollutants’ trapping and the increased PM10 concentrations. The change of the synoptic setting marked the end of the episode.
