Episodes of extreme rainwater pollution and its relationship with synoptic situation (Wielkopolski National Park, Poland)

Abstract

Synoptic conditions of extreme rainwater pollution episodes, evidenced by maximum values of parameters measured in the protected area of Wielkopolski National Park (western-central Poland), were analysed in this study. . It was assumed, that in winter, western advection of Atlantic air masses was the most frequent aerosol and pollution transport scenario for the investigated area. In summer the most heavily pollution occur at the intensified meridional flow over the central Europe, indicating advection of cooler air from northern Europe and the North Sea. In most of cases, the weather conditions causing extreme concentration of examined pollutants, were determined by the movement of weather fronts over considerable parts of Poland and by precipitation caused by those fronts.

“…On the other hand, when peak NH 4 + concentration appearing at two sites simultaneously, this is an indicative of air pollution coming presumably from sources other than local (e.g., 5 and 10 events). Detailed description of the local and transboundary influence of pollution sources over the studied area, present other authors' papers (Astel et al, ; Kolendowicz et al, ).…”

Applications of Air Mass Trajectories

“…In Europe, over half the observed precipitation in Belgrade, Serbia, corresponded to airflow from the SW, SE, and NW [80]. Two flow types were responsible for extreme rainwater pollution episodes in the protected area of Wielkopolski National Park (western central Poland) [81]. Back trajectories reaching four stations in Europe, Oslo, Bremen, Smolensk, and Budapest, for days with the highest amount of snowfall revealed that humid air was transported over long distances and was shifted from the low troposphere to the upper layers [82].…”

“…Thus, it can be assumed that the type of catchment area affects the structure of water balance [16]. Rainwater can become polluted as it passes through the atmosphere [17][18][19]. Falling raindrops catch solid particles from the atmospheric air, as well as liquid or gaseous substances, which to some extent shape the quality of precipitation.…”
