“…The season curve was asymmetric, right-skewed, pollen concentration increased rapidly at all the study sites. Pollen season dynamics was typical for birch pollen behaviour, as it was observed in the previous years, in different regions of Poland [6][7][8][9][10][11].…”

“…It should be stressed that the seasons started almost at the same time at all study sites, the differences occurred up to 1-3 days only. It is stated that the thermal conditions before the pollen season determined the pollination of birches [8,[17][18][19][20]. According to the Monthly Climate Monitoring Bulletin, published by the Institute of Meteorology and Water Management -National Research Institute [21], air temperature in March 2020 was higher than the mean values in 1981-2010 (the reference period).…”

“…B. pendula starts to bloom from the second half of April to the end of May, while B. pubescens starts about two weeks later than B. pendula. Birch trees produce a large amount of pollen (5.5 million pollen grains per the male inflorescence), their pollen seasons are short, but intensive [6][7][8], the total pollen amount contains pollen originating from both Betula species.…”

The aim of the study was to compare the birch pollen seasons in selected 12 cities in Poland in 2020. The volumetric method of sampling was used to collect pollen samples. The estimation of the seasonal parameters was based on descriptive statistics. The clear differences among SPIn values at all sites were recorded. The lowest value was recorded in Bialystok (1.863 pollen/m3), whereas the highest one in Lublin (16.253 pollen/m3). The thermal conditions in the north-eastern part of Poland were the least favourable for birch pollen seasons.

“…The aforementioned correlation is negative and pertains to the cold, wet, and cloudy type NWCC for Alnus, whereas for Betula it is positive and connected with warmer and more dry types with lower anticyclone (NEAC and SWAC). The correlation for birch is visible despite its biennial cycle in SPIn (Grewling et al 2012;Kubik-Komar et al 2019;Tseng et al 2020). Factors recorded during buds' formation (especially a year before flowering) are mentioned as the most important in SPIn modelling (Dahl and Strandhede 1996;Grewling et al 2012;Ritenberga et al 2018).…”

The influence of atmospheric circulation conditions on Betula and Alnus pollen concentrations in Wrocław, Poland

et al. 2020

The influence of atmospheric circulation conditions on pollen concentrations of two taxons (Betula and Alnus) in Wroclaw, Poland, for the years 2005-2014 was analysed. Pollen concentration was analysed separately for twenty circulation types that were determined using objective classification. The results indicate the atmospheric circulation conditions favourable for both low and high pollen concentrations over Central Europe. Pollen concentrations vary significantly according to circulation types. The highest pollen concentrations for both taxons are typical for warm, sunny, and dry anticyclonic circulation types with anticyclone in the lower and upper troposphere, especially for types with advection from the SW. The lowest pollen concentrations are observed for cold, wet, and cloudy cyclonic types with advection from the northern sectors. There is also a positive and statistically significant trend in the frequency of circulation types favourable for high concentrations of Betula and Alnus.

“…The simulations were done for the years 2015 and 2016, which were very different in terms of birch pollen concentrations. The season 2016 in Poland was characterized by high birch pollen concentrations (Weryszko-Chmielewska et al 2016;Kubik-Komar et al 2019). The birch annual pollen sums were several times higher compared to 2015.…”

In recent years, allergies due to airborne pollen allergens have shown an increasing trend, along with the severity of allergic symptoms in most industrialized countries, while synergism with other common atmospheric pollutants has also been identified as affecting the overall quality of citizenly life. In this study, we propose the state-of-the-art WRF-Chem model, which is a complex Eulerian meteorological model integrated on-line with atmospheric chemistry. We used a combination of the WRF-Chem extended towards birch pollen, and the emission module based on heating degree days, which has not been tested before. The simulations were run for the moderate season in terms of birch pollen concentrations (year 2015) and high season (year 2016) over Central Europe, which were validated against 11 observational stations located in Poland. The results show that there is a big difference in the model’s performance for the two modelled years. In general, the model overestimates birch pollen concentrations for the moderate season and highly underestimates birch pollen concentrations for the year 2016. The model was able to predict birch pollen concentrations for first allergy symptoms (above 20 pollen m−3) as well as for severe symptoms (above 90 pollen m−3) with probability of detection at 0.78 and 0.68 and success ratio at 0.75 and 0.57, respectively for the year 2015. However, the model failed to reproduce these parameters for the year 2016. The results indicate the potential role of correcting the total seasonal pollen emission in improving the model’s performance, especially for specific years in terms of pollen productivity. The application of chemical transport models such as WRF-Chem for pollen modelling provides a great opportunity for simultaneous simulations of chemical air pollution and allergic pollen with one goal, which is a step forward for studying and understanding the co-exposure of these particles in the air.
