The pollen grains of ragweed are important aeroallergens that have the potential to be transported longdistances through the air. The arrival of ragweed pollen in Nordic countries from the Pannonian Plain canoccur when certain conditions are met, which this study aims to describe for the first time. Atmosphericragweed pollen concentrations were collected at 16 pollen-monitoring sites. Other factors included inthe analysis were the overall synoptic weather situation, surface wind speeds, wind direction and tem-peratures as well as examining regional scale orography and satellite observations. Hot and dry weatherin source areas on the Pannonian Plain aid the release of ragweed pollen during the flowering seasonand result in the deep Planetary Boundary Layers needed to lift the pollen over the Carpathian Moun-tains to the north. Suitable synoptic conditions are also required for the pollen bearing air masses tomove northward. These same conditions produce the jet-effect Kosava and orographic foehn winds thataid the release and dispersal of ragweed pollen and contribute towards its movement into Poland andbeyond.
