Using data of mean daily values of PM10 and calendar of circulation types for Western Poland drafted by T. Niedźwiedź (2003), made it possible to show the most and least favorable situations occurrence of high particulate matter concentration. The most preferred situation for pollution accumulation is the advection from the southern sector. The lowest values of PM10 appeared in the case of northern types of circulation. It was also shown that exceeding the permissible daily values of 50 μg m−3 (according to Directive 2008/50/EC of the European Parliament and of the Council of 21 May 2008 on ambient air quality and cleaner air for Europe) occur much more frequently in the case of anticyclonic types of circulation. Mean values of PM10 in different seasons, confirmed the presence of the highest concentrations in winter, what is associated with an increase of emissions from municipal sector, as well as increase of frequency of circulation types from the South at this time of year.}, type={Text}, title={Rola typów cyrkulacji atmosferycznej w kształtowaniu stężeń pyłu zawieszonego PM10 w Poznaniu = The role of the atmospheric circulation types on PM10 concentrations in Poznań}, URL={http://rcin.org.pl/Content/65843/PDF/WA51_84760_r2018-t90-z1_Przeg-Geogr-Pilguj.pdf}, keywords={air pollution, suspended particulate matter, PM10, atmopheric circulation types, Poznań}, }
