The aim of this paper is to analyse variations in the severity of Betula pollen seasons, particularly in relation to meteorological parameters at four sites, Poznań and Krakow in Poland, and Worcester and London in the United Kingdom. Results show that there is a significant relationship between Betula pollen season severity and weather conditions both in the year before pollination and in the same year that pollen is released from the plant. Furthermore, it is likely that the magnitude of birch pollen seasons in Poznań, Worcester and London is linked in some way to different phases of the North Atlantic Oscillation (NAO). Significant positive relationships exist between birch pollen counts at Poznań and temperatures, rainfall and averages of the NAO in the year before pollination. An opposite relationship is evident at the two sites studied in the United Kingdom. There were significant positive correlations between the severity of birch pollen seasons recorded at Worcester and temperatures and averages of the NAO during the winter and spring in the year of pollination, and negative correlations at both Worcester and London with similar variables from the previous year. In addition, Betula pollen seasons in Krakow do not appear to be influenced by the NAO, which is probably the result of Krakow having a more continental climate.
本文旨在分析桦树花粉季节严重程度的变化，特别是与波兰的波兹南和克拉科夫、英国的伍斯特和伦敦这四个地点的气象参数之间的关系。结果表明，在授粉前一年以及花粉从植物释放的同一年，桦树花粉季节的严重程度与天气状况之间存在显著关系。此外，波兹南、伍斯特和伦敦的桦树花粉季节的规模可能在某种程度上与北大西洋涛动（NAO）的不同阶段有关。波兹南的桦树花粉计数与授粉前一年的温度、降雨量和NAO平均值之间存在显著的正相关关系。在英国研究的两个地点则呈现相反的关系。伍斯特记录的桦树花粉季节严重程度与授粉当年冬季和春季的温度以及NAO平均值之间存在显著的正相关关系，而在伍斯特和伦敦，与上一年类似变量之间均存在负相关关系。此外，克拉科夫的桦树花粉季节似乎不受NAO的影响，这可能是克拉科夫具有更大陆性气候的结果。
