RESUMO

The study was carried out in the city of Pinar del Rio in Cuba during the period 2006-2010, where the behavior of atmospheric stability and the mixing height was analyzed. For obtaining the category of atmospheric stability the classification according to the Monin -Obukhov length was used. The methodology for calculating the mixing height was based on the procedure in the meteorological preprocessor AERMET, with some modifications for lack of upper air soundings. Also the behavior of the atmospheric stability and the mixing height in the various types of synoptic situations (TSS) were characterized. Finally the hourly and monthly variations of atmospheric stability and height of the mixing layer, as well as the 7, 13, 16 and 17 hours monthly variations are shown. It was determined that the best conditions for dispersion and mixing of pollutants in the atmosphere occur in the summer months and in the daytime, 5PM as the most favorable schedule time.
