The aim of the work was to compare the alder pollen seasons in the years 1997–2017 in Sosnowiec. The measurements of pollen concentration were taken with the volumetric method using Burkard’s apparatus. The impact of atmospheric conditions on the daily alder pollen grain concentration, the annual totals, and the duration of pollen seasons were studied. The dependency between each meteorological condition and different features of the alder pollen season was determined by using Pearson’s correlation coefficients, variance analysis with multiple comparison tests, and the linear regression model using backward elimination. It was proven that the temperatures directly preceding the pollination, i.e. the January and February temperatures as well as those from the period from 210 to 180 days preceding the beginning of the season, have the greatest impact on the beginning of the alder pollen season. The value of the daily alder pollen concentration in Sosnowiec showed a positive statistically significant correlation with the air temperature and sunshine duration and a negative correlation with the thickness of the snow cover and air relative humidity. The daily concentration also depended on the type of the weather front, direction of air mass inflow, and the type of the inflowing air mass. The season temperatures and the thermal conditions which were present in the summer of the preceding year impacted the annual totals (SPI) of the alder pollen grains.

1997-2017年气象条件对索斯诺维茨（波兰）桤木花粉浓度的影响


这项工作的目的是比较 1997 年至 2017 年索斯诺维茨的桤木花粉季节。花粉浓度的测量是使用Burkard 装置通过容量法进行的。研究了大气条件对每日桤木花粉粒浓度、年度总量和花粉季节持续时间的影响。通过皮尔逊相关系数、多重比较检验的方差分析以及向后消除的线性回归模型，确定了每种气象条件与桤木花粉季节不同特征之间的相关性。事实证明，授粉前的气温，即一月和二月的气温以及季节开始前210至180天的气温，对桤木花粉季节开始的影响最大。索斯诺维茨每日桤木花粉浓度与气温、日照时数呈显着正相关，与积雪厚度、空气相对湿度呈负相关。日浓度还取决于锋面类型、气团流入方向以及流入气团类型。前一年夏季的季节温度和热条件影响了桤木花粉粒的年度总量（SPI）。
