A new procedure is introduced in order to separate the effects of the current and past meteorological elements influencing the current pollen concentration for different taxa. The data set covers an 11 -year period (1997- 2007) including daily pollen counts of 19 taxa and 4 climate variables (mean temperature, precipitation total, global solar flux and relative humidity). Results are evaluated with special interest to the interactions between the phytophysiological processes and the meteorological elements for each taxon. The taxa examined can be classified into three groups, namely arboreal deciduous (AD), arboreal evergreen (AE) and herbaceous (H) taxa. It was found that a better comparison can be established if the taxa are separated within each group according to the starting month of their pollination season. Within the group of AD taxa, Alnus, Populus and Ulmus are marked by a late summer - early autumn peak of the role of past meteorological elements exceeding the role of the current ones almost all over the pollen-free period. For Juglans, Morus, Platanus and Quercus, the major weights of the current meteorological elements in the spring and early summer show the most characteristic contribution to the pollen production. For AE taxa, the picture is not clear. For H taxa, the curves of Cannabis, Plantago, Rumex and Urtica indicate the most equalized course of weights. Ambrosia, Artemisia and Chenopodiaceae comprise the highest weights of the past weather conditions of all taxa until at least three months before the start of the pollination.
