The dispersion of fire related air emissions depends greatly on the meteorological parameters and systems which influence the weather conditions at the site of interest. In this study, an interpretation of the physical meaning of the meteorological parameters at the surface, in the upper air and in relation to synoptic conditions is provided in an effort to assess the dispersion patterns of forest fire related air emissions. In particular a variety of meteorological parameters as temperature, humidity, pressure and others, in the fire area, are categorized to describe the prevailing conditions at the site of interest depending on the type of the front (warm, cold, occluded) and the time evolution of the front, the latter as relating to the site of interest (approaching, over the site, leaving the site). Such categorizations may be used in Decision Support Systems for forest fire management
