Abstract
The prevailing synoptic conditions in one place are directly linked to the implementation values of contaminants in the atmosphere. Its study allows to determine the presence of phenomena that favor to a greater or lesser extent the accumulation of polluting substances. Taking this into account, the present investigation aimed to determine the behavior of sulfur dioxide, nitrogen and ozone dioxide in two locations in Havana under the influence of different types of synoptic situations. The data comes from automatic monitoring stations and correspond to time concentrations of the pollutants criteria. From these the daily average concentrations were calculated in µg/m3 and grouped according to the type of synoptic situation that predominated. The sampling period was from November 2015 to October 2016. To determine the relationship with the TSS, the Kruskal-Wallis H test was performed and to study this relationship in greater detail the Dunn test. The maximum average concentration values were obtained when the localities were under the weak influence of the subtropical anti -cyclone of the North Atlantic and the migratory continental anticyclones.
